I think this is perhaps one of the most important experiments anyone could do! A huge amount of information can be learned by running this very simple experiment!

The MrPreva Experiment Circuit

Please Note: The Current's (I), add, Floyd Sweet talked about this specifically:

In the specific case of positive charges moving to the right and negative charges to the left, the effect of both actions is positive charge moving to the right.

Current to the right is: I = da+ / dt + da- / dt.


Negative electrons flowing to the left contribute to the current flowing to the right.

 

The total Current, is the Sum of the both Currents!

 

We see, 2.8 Amps (da+ / dt) + 2.3 Amps (da/ dt) = the shown: 5.1 Amps as Floyd Sweet told us.

We see a Negative Power Factor, where the Voltage (V) Current (I) are out of phase by a Degree, which results in a Negative Power Factor!

cos(theta)

Where theta is the Phase angle in Degrees. EG:

cos(180) =  -1

 

You will see there are some problems with the MrPreva Circuit, and it is explained, because, the Current (da- ) has become a Generator, or a Battery, which is the only time  Kirchhoff's Current Law does not hold in an applied situation.

Here is my replication of Mr Preva experiment using a nanoperm core and some UTP cable.

Cd_Sharp, this is excellent! Thank you for sharing!

Some very simple observations shot:

  • One Globe is very much brighter than the other!
  • The other Globe, although illuminated, has a lot less Current through it!

This is such an important experiment! I wish people out there could see that have not done the experiment! I have done this experiment several times and learnt a bit more each time!

I think I might re-do this experiment for the Forum also!

Hi.  I have a few questions:

Input voltage / amps, how much?

Coil wire gauge?

What capacitor to use?

 

Also, what are each of the white blocks in your replication?  Can I see the entire picture?  Like what the wires are running to as well?  It's easier for me to see it, in addition to reading the schematic.

Thanks for the questions Parkham!

The Blocks: Ceramic Power Resistors, 2.2 Ohms for the big ones 10 Watts, 0.1 Ohms for the smaller resistors, 5 watts.

I just used what I had laying around. Just experiment with it till you get the best result. All my wave's measured were sine wave, so no problem with transients.

My Coil turns:

  • Turns: 175
  • Turns: 88

Note: Turns N, with Current I, equates to the Magnetic Field B, so more turns is better most of the time, just up the Voltage so more Current can flow. The reason I say this, is, its possible to have an experiment where the total Magnetic Field is in sufficient to induce an EMF across the second coil and the Input Current dominates! This means a failure!

This is such a simple experiment, and so much can be learned, if done properly! One can learn a lot about Negative Power Factor, this experiment is the basis for Electromagnetic Induction! Electrical Transformers Work on these exact same technologies!

For someone to say "This experiment does not work", is basically saying that Electromagnetic Induction does not work!

An example of this sort of stupidity:

 

This is Tinman's effort to replicate the Mr Preva Experiment. It simply is embarrassing! He is saying that Electromagnetic Induction does not work!

 

 

After a lot of Down Votes and pressure from people with brains, Tinman tried again, and still failed. Again saying Electromagnetic Induction does not work! Tinmans colleague, Itsu, has however done some excellent work! Showing that, Indeed, Electromagnetic Induction does work as has been stated for some 187 Years, and do in-fact have a valid Law in Nature, thanks to Michael Faraday:

Hey Chris,

I've not tried the MrPreva experiment as I was fairly certain by looking at it that it would not function if pulsed dc was used to drive it directly (without an inverter) and I don't mess with anything AC. Can you (or anyone else) confirm this assumption?

It is a RLC Resonant Circuit, the Cap and Coil Combination are tunned for RLC Resonance.

So DC Pulsing is possible, an Audio Amp driven with a Sine Function Generator is also another good way to do it, I used this method.

As long as the Cap and Coil are in RLC Resonance, then it doesn't matter what the Circuitry is. Switched DC 50% Duty will be difficult to get RLC Resonance depending on the Circuit, so the Audio Amp is a good way to go.

I came back to this experiment because I think I need to learn more about it. Here is my basic setup:

with the yellow trace from the MOSFET gate and the blue one from the drain.

 

Then I unplugged the capacitor and both lights get dimmed a little, but the effect is still there:

 

So, the capacitor is not needed for this experiment.

I was unable to obtain current traces on the two lamps. When I tried to connect the scope probes over the two sensing resistors, input current went up and both lamps become equally bright.

I'm thinking that the cause is that the capacitors in the scope probes are generating parasitic oscillation.

Any ideas on how I would be able to obtain the current traces?

Zanzal posted this 27 July 2017

I've had similar issues with my probes interfering with the circuit, so I just started using 10x and it seems to have helped with that. If your probes have a switch for a 10x setting then you might try that, just make sure your scope knows the connected probe is set to 10x (don't forget to check probe calibration after switching).

Hey Cd_Sharp, Zanzal - Excellent!

Cd, nice setup! The time rate of change is key, of the Magnetic Fields, and if there is not a gradual Rate of Change then yes there can be a lot of funky stuff happen.

For example, a Sine Wave has a gradual change over time, but a Square Wave has a fast Rise and Decay time with a DC (Off Time) in between. This is where the Coils see no relative change. However in saying this, the Current in the Coils do take time to build, ramp up and this can give a similar effect. The following video is an excellent example of what I mean:

 

 

Each little rectangle under the curve is a Change in Time. Lots of small ones with small changes is a gradual Change in Time.

I hope this helps some, I found this helpful when I was studding this. This is why the Cap helped in the Brightness of the Globes...

Scope and the connection, I would only guess there may have been a Ground Loop, shorting somewhere, through the ground connection.

Your two Ground Clips need to be on the same branch. Same piece of wire at the same place. Then you should be ok, unless there is something else going on.

Something like this:

Your Globes are both different brightness's so that is an indication that the Currents are greater in one Branch that the other!

Youre right, this is a very important experiment! If there is anything to be learned, this experiment can show you! It is simple, cheap and very easy!

Cd, Zanzal,

At any one point in time, the Coils in the MrPreva Experiment, Buck Each Other!

They Oppose!

This results in a Gain, in the local Circuit, of almost twice the Current. Try to picture the Magnetic Fields, what they are doing, the Currents, and why they Oppose... Right Hand Grip Rule...

Then look at the other devices, like Don Smith:

For some reason, we, the human mind, has a tendance to way over complicate the simple, We need to force our minds to think simply!

Zanzal posted this 28 July 2017

A couple of thoughts about this experiment:

AC appears to work better than DC. Chris mentioned time rate of change, but I think that's only part of the reason. With AC the circuit is never really "open" (maybe twice per cycle at the beginning and mid points when voltage is zero), but DC pulsed by design opens and closes the circuit and I think this reduces the effect also.

If I am remembering correctly from some weeks ago when I watched the videos, initially both lamps seem to light up about the same, but over time a reverse current builds up along one path causing that path to become a source in parallel with the main source. Not only is the current reversed, but it is self sourced meaning that it becomes its own source.

The experiment does provoke a lot of thoughts on the nature of energy. We all know Ohm's law, V = IR, but has anyone considered that V = J/C (Joules per Coulombs) which is J/C=IR, and that C=I (or Amps per second) which means this can be re-written as J=I^2R. Is V nothing but a manifestation of I^2R? (As a side note, this equation is also the same as the heat in Watts dissipated by a circuit so if you don't know it, you should memorize it for the future, you'll need it to estimate heat dissipation).

Has anyone ever considered why getting voltage is so easy, but most large voltage values are unable to move significant current. We know from the above that something must be missing. Ohm's law must be incomplete. If we can eliminate V and still be left with a missing set of behavior that can only be understood by measuring V. So what is that? V is only the current electrical pressure within the circuit in an open circuit, pressure can build so you can get high voltages even from very little pressure. You can increase the voltage using a transformer, but that voltage can't gain you any current without drawing it from the source.

So what does this have to do with Preva? Maybe nothing, but maybe the experiment proves you can break the rules temporarily even if in the end you never see that it happened unless maybe you question whether Ohm's law was broken.

Of course don't take my word for it. I've only ran the experiment once a few weeks back and on DC. At the time I ran I hadn't even considered these things and had no idea why it was important. This is just me sharing some random thoughts.

I moved my probes to match this scheme:

and I fed a sine wave at 10kHz to the MOSFET's gate. This is the result:

where the yellow trace is the current on the 11 turns branch (weaker) and the blue is the current on the 7 turns branch (the one with the brighter lamp, the stronger). It looks like there are moments when the weaker branch has 0 current, but the stronger one is almost continuously having current.

Excellent work there Cd!

Isnt this the best experiment! It is beneficial in so many ways! With the Magic of the Ocilliscope, we can Click our Fingers and Freeze Time! When Time is Frozen, we can look at the Current, and the Coils, and we can use the Right Hand Grip Rule to see in what direction the Magnetic Fields are. You should end up with this:

 

 This is the beauty of Science, we have most of it correct, we just need to fix some mistakes, typically the assumptions made.

I too am guilty of assumptions sometimes, but I realise that my assumptions are not proof!

cd_sharp posted this 01 August 2017

Sure, Chris I see what you mean.

Generally, the two magnetic fields are fighting each other. There are some short moments on the yellow trace where the current goes slightly negative, so the current on the weak branch partially adds to the current of the strong branch. The other way around never happens.

So, if we could make the current on the weak branch negative for more time we would have a brighter lamp on the strong branch.

I watched closely Itsu's first video and the coils seems to be adding the magnetic fields. Based on this I rebuilt one of my coils and the result is similar. I disconnected the bulbs because they modify the sine wave traces.

I confirm the phase drift and the current difference between the two banches:

Hey CD, the Bulbs likely are pulling more current than the core can handle, the core will be saturating and as a result the globes change the Sine Wave.

The core might be a low saturation core. Its normal. The Sine wave looks like its got sharp peaks at the top and bottom and not much in between?

Really nice job CD!

In fact both coils are ccw, but moving away from each other, so they buck.

Yes. The core material is 3E25 ferrite toroid and you are probably right about the saturation. I'll try with some smaller bulbs.

Another successful replication of the MR Preva Experiment from someone we are all familiar with: TheOldScientist

 

 

If you think careful about the Currents an how this device needs to be in RLC Resonance you will see something really amazing!

When the Coils are in RLC Resonance the current in each coil has a propagation relationship. This as pointed out in the title. Wave Propagation theory is well worth studding. This will make more sense after the video:

.

 

When the Wave propagates, there must be 1/2 Wave Length as mentioned in the video, for efficient Wave propagation.

When the Coils are in RLC Resonance the current in each coil has a propagation relationship.

The formula is:

                        f = 1 / 2 x ᴨ x sqrt( L x C ).

But in this case we have two coils, so we have L1 and L2. Which value should we use?

When the Wave propagates, there must be 1/2 Wave Length as mentioned in the video

Is it about the length of the wire? Or is it about the number of turns? When scaled up to hundreds of turns we end up with several layers and the number of turns ratio does not keep up with the length of the wire.

Hi CD - Very interesting question with some more interesting results!

Some rough math on my setup above, shown below:

L1: 31.8mH
F = 1/2 Pi Sqrt(L C) = 1 /  2 * 3.14159265358979 * 0.00069065186599328 = 230.44 Hertz, So our result is not far away, including the Damping Factor ζ (zeta) 297 Hertz


L2: 16.6mH
F = 1/2 Pi Sqrt(L C) = 1 /  2 * 3.14159265358979 * 0.000498998997994986 = 318.948422204035 Hertz

I simply did not take this far enough, this was quick and dirty guesses with no verifications at all. I did not check L1 - L2 = Lprime as the Inductance for the equation, although I should have...

Why should I have done that? Because each Inductance will cancel... Maybe we could do this here?

Either way, we are still some ways out from the resonant frequency even with the Damping Factor.

Edit: Oddly, if I half each inductance, then add the two, I get: 264.16Hz

Hello and welcome Blackboarddd!

By experimenting with the Coil winding direction, you will find there is one way that works best in this configuration. I suggest increasing the turns to a greater number, making a little more work, but it is easier to get a result and learn from this very valuable experiment.

The Magnetic Field (B), changing in time (dt) in the proximity to the Turns (N) is the catalyst for Electromagnetic Induction. With Few Turns one will need a great Magnetic Field at High Frequency.

Yes, the windings in the Mr. Preva setup oppose. IMO, this experiment works much better with AC than it does with DC.. Pulsed DC results are a little fickle and while you'll still see one lamp brighter than the other, it may be harder to measure what's going on or determine if you are in resonance. With AC it will be much more obvious and you'll see the two coils are completely out of phase (when in resonance).

I think some of the videos the core was said to be nanoperm. I've not personally tried successive testing with the same setup varying only the core material so I've got no insight into it.

Chris has recommended others to use whatever they have handy - this is the best advice I could offer you. I've asked Chris several different times and different ways and what I've learned from him is that there are no magic core materials but there are sometimes bad core materials that can cause an experiment to fail. If you have trouble with one core material, you might document it and try another.

Hey Wistiti - I have build variants as you know. Youre right, this device is very similar to the Mr Preva Experiment:

 

Voltage is a quantity, as is Current, Electromagnetic Induction is a process that Transforms Voltage and Current. However, as we both know, this is not terminology that accurately describes the process!

Electromagnetic Induction produces a quantity of Voltage, which is E.M.F, Electromotive Force, it "Generates" or Pumps Voltage and therefore Current in the Second Coil. But this is not even entirely correct! Because this is a One to One process, less losses, we will always see a drop in total power. The Losses need to be over come by the Excess "Generation" or Pumping of Voltage and Current.

Current is Magnetomotive Force, M.M.F, and this Force needs to be off balanced by an Opposite force, to counter the One to One ratio less losses. In other words a Asymmetrical System instead of a Symmetrical System!

This is an old video, it was a year or so old when I posted it to YouTube. Its some of my early work:

 

Moving from a Square wave to a Sinusoidal wave is a start to seeing Energy Generation.

This is all stuff you already know, but for the other readers, they may find it useful.

Hello Wistiti,

Please consider that little curent in vs. more current out, does not necesarily mean what most people call ''Overunity''.There is also Voltage and the phase difference between Current and Voltage. Do you have an osciloscope? If not, the least you could get is a wattmeter. Now...by putting the wattmeter between the wall and your input you can get an idea of at least the power being put in. If u take the only consumer to be your bulb, than you could judge the power it has flowing thru it by its light intensity(at least for 50Hz is ok), but I would recomand an osciloscope.

Learning to Amplify Current is perhaps the largest step forward. Wistiti has kindly shown this step forward along with others like CD_Sharp and others.

I will go through the thread again when i get some time off to really get an understanding of the concept.

I haven´t did any coil measurements, or RLC matching, or anything like that. I just took what i had laying around, but i will in the future try to make it more like Chris has outlined in some of the schematics he has posted.

My L1 and L2 are thinner wire, and much more turns, + they are about the same regarding turns, mass and all that, but i saw that Chris had done that in one of the others he posted, so i went ahead.

Basically, we see the Current Double in the Circuit, thus the term used above increment of current. This is an Auto Transformer of types.

When youre happy this makes sense toyou, and if you need, please ask questions, then my next thread: Some Coils Buck n some Coils DONT will help with further understanding!

Chris mentioned to me that very few people have taken the time to reproduce the Mr Preva experiment. Thought I'd share mine. Redid it real quick. This is not the AC variant so my waveform is not very interesting. Finding the resonance point for parallel resonance was as simple as dialing in the frequency into the lowest current draw. Here is what that looked like:

Awesome Zanzal - Thank You so much for sharing!

Please everyone, this is a very important experiment! Please take a few minutes to replicate this experiment, then one can take many long hours studying the Results! It is an invaluable Experiment!

Thanks again Zanzal! This is excellent!

So this is a bit random, but I thought I'd post a experiment for those who really like the Mr Preva concept and are looking for something interesting to try: 

Would an induction heater be more efficient if two coils are used in a style similar to Mr Preva?

Hey Zanzal,

Your question:

Would an induction heater be more efficient if two coils are used in a style similar to Mr Preva?

 

 

Answer to your Question: No, not as it stands.

 

@All Readers:

As we know the Mr Preva Experiment, is Symmetrical, it has equal and opposite Energy Transformations less losses. This is the reason it is, as it stands, Below Unity! Experiment shows: Current is Amplified, but we see a large Voltage Drop!

Electrical Energy is V x I, by loosing one and gaining another, does not constitute an Energy Gain! However, amplifying Voltage does not cost us anything! This is not a Transformation of Energy! No work is done to Step Up Voltage!

The next Step to The Mr Preva Experiment, is my Thread: Some Coils Buck and some Coils DONT

I introduce the Asymmetrical Energy Transformations, where the Input Energy is not affected, in anyway, by the Output Energy. This is the reason I have posted the Thread: Asymmetrical Regauging.

I see many are not seeing what I have been trying to show, many are not following the trail, not understanding posts I have taken time to detail effects and show where the open doors are. Its ok, I am ok if others do not want to learn.

However, if people want to learn how Energy Machines work, they will need to learn, need to start thinking in terms of Energy Transformations, learn how our Environment can introduce excess Energy!

Your Input of X Energy, is never, ever going to Transform itself into 2X Energy by itself!

You must Open a Door for the Environment to Add Energy!

The Door = Increasing the Rate of Kinetic Energy

Hi Chris,

Could you explain  "I = da+ / dt + da/ dt" . I know I = current. However I don't know what the rest is. Derivative of something with respect to time. da+ and da-.

Hi, P! If I may, da+ / dt is the current flowing from the power supply and da/ dt is the current being "generated" by the bigger coil. If you wish, generally, da / dt  is the charge amount moving during the unit of time, in other words, electric current.

Hi P,

CD is right, da+ and da- is the change in Charges, both Positive and Negative Charges. If you have a look at the quote from the document, there is direct reference to Charge in the Conductor and its movement over time.

I have had a few people try to argue with me on this, trying to explain this away as nonsense, the funny thing is its a proof of concept experiment that can be done on the bench in 10 minutes.

There is only one site I have come across that has Current ( I ) depicted correctly:

Ref: http://33elec.blogspot.com/

 

All sites say a Capacitor has two charged Plates, one Negative and one Positive, but the depiction of Current is a singular entity with singular flow... Surely and misconception in Electronic Engineering that has been missed by the masses!

Reading this thread a few times and doing the experiment it all makes perfect sense. A logical sane mind can not argue with proof!

I agree. in the 1900 they found out current runs from - to + (JJ Thomson) but were to lazy to change it. i do not believe this as the misinformation was there to confuse your average person or researcher, this was done purposely. i have done my own tests that does prove it is so. while i still disagree on the whole electron thing and it's origin i will concur current does run from negative to positive. Negative is the Pressure, Positive is the non pressure thus will always flow to equalize. without positive non pressure current will no flow.

A couple of thoughts about this experiment:

AC appears to work better than DC.

Square-wave AC works best in my testing. The effect is highly dependent upon the ratio of turns in the transformer vs. the frequency vs. the capacitance. It seems sometimes the magnetic induction overrides the ability of the voltage to push through both coils in the same direction, and sometimes it doesn't, dependent upon the parameters mentioned above.

If you get your capacitance and inductance just right (ie: hit a resonance point), you can get more current flowing through the second winding than flowed through the first (the second light is brighter). I'm unsure why it acts this way. Parametric resonance?

Could there be some forward biasing involved like that of a mag amp,  more so at certain frequencies.?

Hi Prometheus,

Good to see new members joining to the forum ,participating and experimenting! I have also done some tests with the mr.preva experiment and similar circuits with diodes and found that the interaction between the coils and the timing can be changed by varying the parameters, although i have not found the explication yet.

Ahaha! Here's a pretty good explanation:

We provide the "wind", the transformer is the "lake", the standing waves are the two current directions, but we're pushing the 'waves' high enough that they overflow the 'banks' of the 'lake'.

It's a rough analogy, but it helps to understand what's happening. I wonder if you had a center tap on each coil with a diode, connected to ground such that you could pull electrons in from ground? You'd have to drive it pretty hard to get the node of the standing waves below 0 volts such that electrons are pulled in from ground, but it could be done.

If it works, I propose we call it the "Moses" transformer (think of Moses parting the Red Sea).

If you re-read the beginning of this thread, you will understand how the MrPrevna experience works, which is the reality, please Moise that I respect should not be mingled with our discussion.

Prometheus, The principle how the mr. Preva experiment works "normally" is straightforward, the current flowing in the direction of the coil with less impedance, and the opposed magnetic field makes the current in the other coil flowing backwards, I did understand that you could reverse the direction, which would be certainly a very odd behaviour.With the other direction I mean the lamp on the coil with more impedance would light brighter.

Jagau and Vidura are Correct!

There is no complication to this! The principle is universal, the Time Rate of Change of the Magnetic Field, which is analogous to Current:

 

V = L di / dt

 

Voltage ( V ) is the product of the Inductance ( L ) multiplied by the Time Rate of Change ( dt ) of the change in Current ( dI ):

 

Where does the Excess of Current come from, Electromagnetic Induction! We see the exact same principles in Circuit Theory:

 

 

Parasitic Inductance, something Engineers have struggled with for ever. They try the best they can to eliminate it, Truth is, its always there, they can only ever reduce it! Its the Time Rate of Change of the Magnetic Field, Electromagnetic Induction inducing Voltages on Traces that are close and as a result stray signals interfere with Circuits, an unwanted situation, thus the term Parasitic!

I see Confusion, and posts that are over complicating simple straightforward fundamental Science! Please, ignore complication, a simple answer exists for all things!

 

Vidura and Jagau are correct, we have a simple explainable and provable answer, there is no need to make simple things complicated!

You can see the circuit which posted Chris in the thread "finding the resonant frequency of a LL resonant circuit", it has no centertap, is similar to the mr. preva circuit,but the current is forced in opposed direction by diodes, and it has no tank capacitor. In this thread you can see a video from the experiment I had posted. Regarding the electron pumping CDsharp has posted a experiment where he could do this in a very similar circuit, first it appeared that the current was flowing against a diode, when he searched he found current flowing to ground(electrons out of ground).I don't remember exactly which thread, it was a couple of months ago.

Hey Vidura,

Do you mean the Thread: Some Coils Buck n some Coils DONT

You're right, many threads here are based on this Thread! I think most here would agree we have broken ground, we have thoroughly investigated this and we have volumes of data on this phenomena!

Yes, CD's Thread also is based on this Tech: Finding the LL resonant frequency

I don't want to bore the members that have already read and researched this Tech, but for the new comers, there is a lot to be learned! A lot to experiment with!
