Toroidal cores are always wounds with the windings 90 degrees to the circle of the core. They only create a magnetic rotation clockwise or couterclockwise in the core. This this can basically be modeled with as a system with 2 dimensions : field density, and direction of field (in a nice bifilar coil)
But we can do better than that, and nature does better. Let's make it a 3 dimensional system. Let's put a rotational bias in 1 direction on the ring's magnetic field, with the standard windings. Bifialar to keep distributed capacitance equal. Now have a solenoid coil in the center of the toroid! Make this one oscillate. We now have a vortex, just like when you start one in a glass jar with some water, and look at particulates floating around....round and round in 1 direction....up and down in the middle. but wait! gravity bias needs to be accounted for! maybe a magnet at one end!
Toroidal cores have been used extensively by jewel thief makers. I suggest this design be used as a jewel thief. If all resistors in the circuit were replaced with inductor coils, around the core, and the oscillating part of the circuit were to be placed inside the torroid, maybe with its own rod core in the center,.....we might have something interesting.....
Seems like the dc winding around the core could be used for magnetic amplification purposes...
and if you don't do exactly 90 degree offset from the dc control coil and the ac coils in the center, you can have some kind of partial coupling between the them, with a regenerative effect going back into the outside rotation.
