The most simplest way to boost up magnetic field for any electrical machine need it is to use wire with higher Specific resistance than cooper.
For example for a given lenght of 1meter. diameter 2,5 mm, same Nichrome wire or nickel-chrome alloy wire will have several times stronger magnetic field in comparison to same wire with same diameter from cooper. for a same giving current density for example from accumulator source 12V, 30Ah.
Simple experiment 2 wires - Cu and NiCr 1meter in lenght, same diameter 2.5mm, 1 accum.battery 12V/30Ah, 1 oscilloscope, 1 hall-effectl sensor, 1 resistor 10 om 10W. Just setup and meassure. Same conditions for both, same setup voltgae and current but very different magnetic fields around. As you guess specific resistance is responsible for this difference.
Off course using complex winding techniques like Tesla bifilar, magnetic field can be boosted more higher. The trick is to make much complex 3D formes like Tesla have had in his experiments with so called Radiant cone. There is one particular picture of it with Pure Silevr Radiant Rays running from the top of his bifilar or maybe multifilar Radiant cone. If you get violet or bluish rays it means you have no radiant but electron flow. Keep your head and hands from high energy electron field.
Read Tesla - he is Radiant Guru #1.
