I thought it was clear enough. I doubt it being more effective than a
standard coil, but that's not the point, eh? The main problem is going
to be the very high speeds required of the magnets. For a 200kHz coil,
the magnets need to spin at 200k rpm. For .5cm radius magnets, now we
have a tip speed of 1 km/s, which requires PBO reinforcement and a
vacuum chamber. Somehow this seems impractical.

However, if you used a cored tower coil with an extremely low fres,
then you might be able to make it work.
