This is really a lot of things all at once.
1) Toroflux coils; Lots of pictures here http://www.overunity.com/13925/toroidal-coils/#.UoP-nPm23zE Video links there too...

They are the same as Nunez's unification coil; one turn around the toroid and one turn through. Once you wind the whole thing, you need to back the first end out until it's not cross wound (usually 2 or 3 turns) then rewind it. During the process the tail sometimes gets caught on the wrong side of loops.
Using a fairly stiff wire makes a stable shape that can be contracted in the center or expanded to just a ring... it can also be inverted in the middle, so there's 2 points that are focused magnetic regions.
I've been playing with these coils of just a few turns and getting really good inductance results.
(early beginnings)

2) alternative geometry for a magnetization coil. (SEG Magnetizer)

This will make predominantly a n/s pole, but with skews on the edges... I dunno there's not much to that thought. (I think it would work, but I dont have a good material to make a magnetic imprint using such a coil).
3) I started with a set of small coils, and a signal generator, and got a fair amount of voltage out of them in a resonant condition...

4) I've been experimenting with these coils and a mazzilli ZVS oscillator... I think that I can chain this and get some output.... (without ferrite core/ with air core)
