Something interesting to consider.
If you imagine a figure 8 as a twisted loop, making two loops, and run a current through it, you will get a magnetic pole going into one loop, and coming out of the other. If you rotate this shape on its axis (imaginary line drawn between circles 8<--) you get a toroid, where the magnetic spin is always in one direction.
If you run alternating current through it, it will create a pole at one end, and an opposite at the other, then it will switch, creating false rotation, much like a single phase motor, with alternating poles. If you wind it so that the loops are not 180 degrees appart, maybe only 120, then you create 3 "poles" which alternate in sequence nns, snn, nsn, and so on creatingn an unbalanced rotation. As long as you keep the wind pattern where it comes over the toroid, through the center, then back around an opposite section, this effect can occur. There are many winding configurations this could be tried with, if you keep the premise of the winding the same, where the same current creates alternating poles with each wind. Things could get really interesting when the frequencies used physically start to match the natural parameters of the coil.
one could very well wind in a high impedance, high Q, bifilar wound coil which will have a large SWVR causing large reactive currents.
just a thought.
