Folks, this should not be this difficult. I mean, magnets, high voltage flybacks? Square coils? exotic or dissimilar metals? This can all be done if you want to spend the next decade working on this thing. But if you extrapolate the information from all the players here it is clear that none of that is needed.

The culmination of 60+ posts is:

Physical:

1 coil of copper of 3-10 turns 3" to 7" diameter of guage 12 to 4 wire or tubing.

4 control coils wound 90 degrees to collector coil and 90 degrees in circumference to each other. 30 to 18 guage wire.

Electronics:

It's clear now that all this needs is a circular CCW pulsing system controlling the four coils. Using NPN transistors or mosfets with decent timing in between each coil firing. 300mA or less per firing at 5VDC. Timing done so that the collector doesn't stay in complete saturation but rather has clear pauses between each coil firing. This being air core means that even 5Khz is slow compared to what the air core could handle, but sufficient for creating the effect. LC resonance? I don't think it's needed. If the extra amplification is desired then it's easily obtained by slightly increasing power levels to the control coils, or adding a calculated capacitance to create an LC tank.

See attached simple pulsing circuit to get the idea. This is where I am working. The second circuit I am building will be a microcontroller based system where more precise timing can be achieved, but I honestly don't think it's needed.

Flow with the microcontroller would look like the following:

Automatic mode:
1. pulse coils 1-4 and check collector coil output via AD converter.
2. Continue to increase frequency as coils 1-4 are fired.
3. Record collector output power levels and continue until maximum voltage is recorded.
4. Once highest possible voltage has been found, check temperature of collector coil via AD converter. If heat levels are higher than ~150F then decrease frequency until heat level drops, sampling every 1mS.
5. Post temperature, voltage, and frequency to LCD screen.

Maybe I've missed something but it just doesn't seem like it needs to be changed six different ways to sunday in order to get it to work. When I say work I mean produce 2x the input. Even this would be miraculous to an engineer but it's clear from the videos and information that it should be easily possible with this configuration.

In the above schematic the system works as follows:

Function gen fires coil one. Coil one has a feedback winding of 3-5 turns. This feedback fires NPN trans on coil 2, thereby firing control coil 2. Coil 2 has a feedback same as coil 1 that fires NPN trans on coil 3, and the cascade effect continues.

Frequency from the generator controls saturation of the field and thus the magnetic wave that encircles the collector coil. Frequency is changed manually until highest voltage on collector is obtained. Frequency is recorded and the freq gen is swapped out with 555 timer or some other form of pulse train circuitry that is then fixed at the optimum frequency for the given coil.

Getting set up to build. Circuit should take 8 hours or so to build and tune. Would be nice to see what results have been found by others in order to minimize time wasted.

Microcontroller based system will only be built if first circuit shows a small but measurable output on collector coil.
