Inductance ( L ) is the Rate at which Amperes can flow through the Coil in Time, this is defined as:

L = di / dt

One Henry is where One Ampere transitions the Coil in One Second. With Back E.M.F: 

L = ε / di / dt

Where ε is the Back E.M.F, restricting the Current Flow, created by the change in Current  that produced the E.M.F.




Keep reading:

The Impedance of a Coil is calculated: Impedance ( Z ) = Voltage ( V ) / Current ( I ) and is given in units of Ohms ( Ω ).

Complex Impedance has two components, real and imaginary. An example of this would be: Z = R +j X


  • DC Resistance ( R ) = Real Component.
  • Reactance ( X ) = Imaginary Component.
  • +j = Voltage Leading.
  • -j = Voltage Lagging.

All components are real components, observable Circuit conditions.

Reactance ( X ) is composed of both Capacitive Reactance ( XC ) and Inductive Reactance ( XL ). In an LC Tank Circuit, at Resonance, XC and XL are equal and are said to cancel each other out. Thus in the LC Tank Circuit, the Capacitors Charge ( Q = C / V ) transforms into Magnetic Field ( B = μnI ) at maximum efficiency, which is measured as Quality Factor ( Q ) = Reactance ( X ) / Resistance ( R ).

So, if Reactance ( X ) is very low, say: 0.00001, and Resistance ( R ) is very low, say: 1.0, then Quality Factor ( Q ) = 0.00001 / 1.0 = 0.00001

NOTE: Inductive Reactance ( XL ), is directly related to Faradays Law of Electromagnetic Induction!



Faradays Law of Electromagnetic Induction: E.M.F = -N dPhi / dt, which is actually Back E.M.F, because of Self Induction inside the Coil, between the turns, this resists the Flow of Current, B.E.M.F = XL = ωL = 2pifL

Also, remember, B and H are related in the following way:



We know, the Cycle of the Transformation from Electric to Magnetic can be seen in Quadrants:



Red is Charge on the Capacitor ( Q = C / V ) charging the Inductor ( B = μnI ). At 90 degrees, the Capacitor has fully charged the Inductor, and the Inductor now Charges the Capacitor as the magnetic Field Changes in Time in the proximity of the Turns, yes Faradays law of Electromagnetic Induction again.

In an LC Tank Circuit, we see losses, Damping Factor ( ζ ) Zeta, and we see a typical decrease in the Amplitude of the Oscillations in an LC Tank Circuit:


Inductance and Reactance all stay Linear, losses are not recoverable, and we see the Oscillations taper off.

However, what is required to change, to Non-Linear Inductance? How can we see changes, enough to see a wave form like so:



Knowing what we know, we must have any one of the above variables change. An experiment I have done, does show how this can be achieved: Reduced Impedance Effect

I do not agree entirely with Jim Murray. He has found a lot of what I have, his Transforming Generator does show the same effect as my Reduced Impedance Effect:


In the following video, if you listen carefully, Jim does say what I have, I = dL / dt:


So, it is possible, at 90 Degrees, we can change the Circuit, make the Circuit change, with The Reduced Impedance Effect, or other effects, to become more Re-Generative, or Less lossy.

But, please remember, we must not touch the Circuit between 0 and 90 degrees, and between 180 and 270, all Red Zones are No Go Zones!

By changing the Systems Inductance or any part of the Coils parameters, which in turn changes the Inductance, is a common theme we have seen a lot of.

The works of Don Smith, Floyd Sweet, Andrey Melnichenko, Clemente Figuera, and many others all take advantage of these effects.

Also similar to Zanzals Un-Named Device, also a Video Zanzal has shared:


This Technology is everywhere, its there for the taking, it only requires you understand these concepts and then apply them!

I think the term: Non-Linear Inductance is perhaps not entirely adequate for the description of what's actually going on. So I ask you, please think broadly about this and do not confine yourself to the specific of Inductance.

What is true, if we change the Rate at which Current can transition the Coil, we have also changed the Inductance!

One more thing I would like to add to the above.
Nonlinear energy storage elements may be:
1. capacitance diode, i.e. the capacity depends on the voltage applied
Rectangular iron core = nonlinear inductance ie inductance is a function of the current flowing through the coil. L (i)

This is a similar layout, but there is currently no secondary impulse here.

Other possible layouts.

To get a picture of what Chris said above, I would add this:

Resistance; is essentially friction against the motion of electrons =  express by R a scalar number

Reactance; is essentially inertia against the motion of electrons = express by Xc or XL a complex number

Impedance ;is a comprehensive expression of any and all forms of opposition to electron
                    flow, including both resistance and reactance = express by Z sum of scalar and complex number


hope this help to understand

To stay in the same idea:

Regarding the nonlinear inductance I noticed in my experimentation that when I use ferromagnetic cores there is a saturation effect that occurs at a certain voltage exceeding the saturation.

Beyond this saturation point we find the non-linearity, it is this section which is difficult to control and to predict it is the one that sudden jumps of voltage and current occurs and this is what we are looking for .

When I did experiments on the generator of don smith the aircore never saturated.

Ferromagnetis material saturates but not air coil.

My Friends,

Atti, Aloha and Jagau are exactly correct!

Atti, awesome experiments! Thanks for sharing!

Aloha, you're right, the Kapanadze Grenade is a Non-Linear Inductor, as the Current changes so does the Inductance, this effect is very much more pronounced at Resonance. Current reaches its greatest value at the resonance Frequency.

Jagau, thank you, I completely agree! The hysteresis Loop, the B H Curve, up at the Knee, this area is inherently Non Linear because it is moving in and out of Saturation.


Normally, the linear sides of the B H Curve are used and the Cores are not normally driven into Saturation, or anywhere near it as a matter of fact. Marked as "Turnaround Point"



Once Saturated, the Inductance is gone and the Coil presents a simple Resistor, Current can flow through the Coil with no Reactance ( X ). This is how a Saturable Reactor works:


I know you know all this already, but for others reading that do not.

You have made Non linear coil. Question is on which frequency you need to match two traveling waves to get standing wave.

Standing wave is a spatial distribution of nodes and antinodes of current and voltage in the coil

Standing wave calculator

Hey Jagau

Maybe you should try bistabile ferrites with square hysteresis loop ?

Question is why we need to match LC resonance for example from Blue Granade and Standing wave resonance (resonance point where stading wave formation ) is guaranteed ?

Answer in this picture

This is how matching is looking at oscillograph screen.

Upper ray trace - Single pulse excitation. Voltage between ends of matched LC&SW coil. V=20V/div, Timebase = 500nS.

Bottom ray trace - monopolar (unipolar) pulse which run between coil ends, reflect multiple times and fade out.

If you have understood this, you will know why Great Tesla said: "I don't radiate enrgy from my coils (strimers, sparks, corona, etc. etc). I collect energy to huge ammounts and if i need i release that energy in an infinitezimal moment of time.".

ps: This is where has hidden the real power. Keep i mind this is only one pulse excitation.!

Best regards

My Friends,

Aloha is entirely correct! We have covered many times the Standing Wave phenomena! Again:

Electromagnetic Wave:



The Direction of the wave is in the direction of the Blue Arrow. The Wave Length is: λ = v / f - Where v is the speed of light in the medium one is using, and f is the Frequency.

Please forgive my inaccurate depiction, but the following is supposed to show two waves equal, but travelling in opposite directions, the Arrows in the Current Waveform are in the same direction:



However, the Arrows in the Magnetic Waveform are in opposite Directions! 

Of course, the top and bottom waves in the above Image, when combined, create the wave below: A Standing Wave is the Current depicted in Green, which has double the Amplitude of each wave by itself.


Standing Wave:


Two Wave Forms, each in opposite Directions, shown by the Blue Arrows. In this case, equal in Amplitude. However we see the Current Waveform, depicted in Green as ( E ), has double the amplitude. This waveform is a Standing Wave, two Current Waveforms traveling in opposite Directions Summing.

The Wavelength for a standing wave is: 0.5 λ


My Friends, it is true, the ideal situation, to bring about Non-Linear Coil Conditions, from 90 Degrees on to 180 and from 270 to 360, a Coil, Bucking, Current in opposition, or Partnered Output Coils is one way to achieve these results! 

@Aloha, Current is the Flow of Electrons, and only when a Load is connected can Current flow. When I quoted Ruslan's quote:

2. You need from Tesla only one half wave. Otherwise Tesla will take what she gave, back !!! Therefore, and put the diode from the ground to the very take-off coil (40m) The shark did this at the reception. He removed one part of the sine at the reception itself.

Ref: Ruslan's Flashlight without batteries


An answer was given! Ruslan is a smart man, some have said he has faked his devices, I believe none of that! I am very confident he has what he says!

My Friends, you're all completely awesome! I hope now you see why I have said we are light years ahead of the other Forums! We truly are! Please ask questions and we will do the best we can to answer! NO ONE gets trolled here!

Hey aloha
excellent discussion
I never try this type of bistable ferrite because it think it is used in frequencies like mcrowave and gigahertz range. Also with the square shape BH also offers a desirable saturation it's just the shape of the curve that changes.
Maybe want to explain more to me what do you mean?

For Tesla yes he used extreme tensions with spark gap that gave him instant energies very great unfortunately I do not work with this kind of tension, maybe one day? Aloha greeting.

My Friends,

This Thread, without a doubt, is perhaps the most important Thread ever posted to any Internet Forum ever!

The Change of Magnetic Field, which in turn is the Change in Current, the Change in Current Induces an: E.M.F, a Voltage in Conductors: Self-Inductance, and or Mutual-Inductance, all subjected to a Reactance ( X ) to the initial Change in Magnetic Field.

In a Coil, there exists Force between the Wires carrying Current, there is a polarity to this Force:




NOTE: This Force, is not present unless there is a Change in Current and thus a Change in Magnetic Field.



The Copper tube is Conductive, it does not carry current at all unless the Copper Tube has a Magnetic Interference, this is Electromagnetic Induction!

NOTE: The Copper Tube is not a Source of Current until the Magnetic Field is changing in its proximity, the Currents Changing, or the interference between each other, the Change in Magnetic Flux and the Conductance of the Copper Tube, "Generate" an E.M.F and thus the ability for Current to Flow, the Current is a property of Conductance, not the Magnetic Field!

This is the exact same effect as Self Induction, where the change in Current produces an E.M.F in between the Coiled Conductor, the Wires inside the Coil:



We have seen the Video, the Lorentz Force, several demonstrations:


We have Resistance, Resisting the Change of Magnetic Field, at all stages of Electromagnetic Induction in the form of Reactance ( X ). This is a direct Energy Exchange, Current passing through the Resistance in the Coils, this Energy Transforms into Heat, so Coiled Conductors Heat up as the Current through the Resistance dissipates the Energy.

Newton's Laws of Motion, especially the Third Law, gives us the Secret to Limitless possibilities: For every Action there is an Equal and Opposite Reaction, I have extended this to: and Every Reaction has an Equal and Opposite Counter-Reaction

The Secret is Potential, once we have bought the Potential Up, the Reaction can be Counter-Balanced by a Counter-Reaction.

Think of the Conduction of an Insulated Copper Wire, or a Copper Ring, or Tube! There is no Current Flowing in the Copper at all, until it is interfered with. The Change of Magnetic Field is present no matter what happens, it is part of bringing the Potential Up!

This Potential must not be interfered with, its a Prime Mover, the disturbance in the System, to shift the point of Equilibrium. Floyd Sweet gave a figure of genius:



What goes up, must come down. This we have covered many times. Many different places. One Thread comes to mind: Increasing the Rate of Kinetic Energy.


Important: Our Counter Balancing Force I call: Reduced Impedance Effect



The Forces in the Wires: Forward E.M.F ( Red Arrows ) and the Back E.M.F ( Green Arrows ) are Newton's Third Law in Action: For every Action there is an equal and opposite Reaction!

So we can use The Reduced Impedance Effect to Counter Balance the Back E.M.F ( Green Arrows ), this is introduced as a Third Force!

When Two Coils are positioned in such a way to Buck each other at a specific point in the Cycle, the Coils interfere with each other in exactly the same way the Permanent Magnet "Generating" Currents in the Copper Tube!



There is a Linear response, the Magnets Distance Traveled / Time, this is the direct result of Lenz Law, but not between our Input and Output Coils, instead this Counter Reaction occurs between two Output Coils, the Forward E.M.F is reinforced, or another way to look at this, using Superposition, is the Magnetic Field Vectors of the Back E.M.F in each Coil are Canceled, they Sum to Zero.


This Linear Response is seen as a Saw Tooth Waveform. This is Lenz's Law in Action and is directly seen as Velocity of the Permanent Magnet: Distance Traveled / Time, the Time is slowed dramatically due to the Resistance, the Reactance ( X ), to Change of the Magnetic Field. This is what Tom Bearden called: Asymmetrical Regauging

Ironically, this is information we have been given by those before us:

The magnetic flux from the two secondary windings cancels in the "outer leg circuits," leaving only one-quarter of the total flux generated by the output current to react back upon the primary. This resulted in a current gain in the secondary, relative to the primary. Lenz's law was bypassed, and free-energy resulted. An alternate explanation for the current gain in the UDT is to consider each secondary winding as acting as the primary winding for the other secondary winding when an output current is drawn because the two secondary windings generate geometrically opposing fields.

Now consider the "feedback winding." It is connected in series with the secondary and is wound over the primary winding on the centre leg of the core. When the core is magnetized, an induced voltage will appear across the feedback winding which will subtract from the voltage across the secondary. The purpose of the feedback winding is to cancel the remaining secondary flux passing through the centre leg of the core. It effectively isolates the currents in the primary and the secondary at the cost of a reduced output voltage. The feedback winding generates a magnetic flux equal and opposite to the residual magnetic flux from the secondary when an output current is drawn.

Ref: Paul Raymond Jensen


We know Floyd Sweet did have the privilege to study Paul Raymond Jensen's machine. Documented in the Reference link above.

There we have it, we have the ability to change the Inductance at any point we wish, or change the Reactance, the Coil can be Controlled, the Transition of Current through the Coil can be changed by introducing another Equal and Opposite Magnetic Field, an Induced Current, just as the Magnet falling through the Copper Tube "Generated" an E.M.F, we have Coil Conductors doing the same thing.

May still Edit, stay tuned...
