Scratch made field effect tri-coil

Just something I've made a while back when bored. I dub this construction the field effect tri-coil. What it does, who knows? But I think that running current throught the wires causing magnetic fields to bend in "unnatural" ways would have interesting effects. The funny thing is, the device is ridiculously simple to construct. (Nothing beyond anything Tesla could have done in half a day.) It consists of 3 interleaved wires. First one is the power wire. It's heavier guage and wound into a flattened and layered spiral ring as shown in the diagram. This wire provides the primary field and should carry the heavier current if is introduced into experimentation. The second wire is the compression or intensity wire. It's wrapped in a unique way (clearly illustrated in the diagram), presumably to break up induction in itself while compressing the field of the primary coil. The third coil (in this case it's a simple 5-point star configuration, although there may be better wrappings) is the torsion or vortex coil. The idea is to induce a rotational tension in the field.

Now for feeding power to the thing... The controls should be pretty simple/stupid, although the resulting effects might be chaotic or interesting. Each coil gets 3 input dials of its own for the power supply. First one is level. This should be a simple voltage control that influences the peak amplitude of the waveform. Second one is beat, or frequency. A beat of 0 would be a constant voltage based on level, and then it's an adjustable sinewave from there. The third one would be phase. So you can shift the waveform and alter the interaction of the harmonic beat frequency of each coil independently. Available current should be fixed at some level, because the other parameters should be plenty enough to observe for magnetic tension effects.

Here's a schematic diagram. Ultimately, if the device was useful, this schematic would be used in a manner much like the ReacTable video synthezier interface and be operated by a smart touch screen. What's neat is that you could add modifiers, and link arrays if a more complicated system used multiple tri-coils. It would allow quick flexibility and great variety of waveform mode operation in a quick to read visual format. Data could be displayed as a graphic associated with the component or as a numerical readout.

As for what it does? Untested. But it might make a really unique induction coil. It might provide some secondary field effects. Or it might not do much other than make wires hot. But hey, it's really cheap. And wouldn't it be great if it actually did something useful?
