Hi Bill!

I don't think it would oscillate since there are no LC components
involved, but if I interpret correctly what your saying, then you
may want to try this idea:

Wind a 3 to 4 inch diameter flat pancake spiral wound coil with 22AWG
magnet copper wire with a centre hole fitted to the O.D. of the magnets.
Center this coil over the magnet gap. Apply a chopped D.C. current
from 3 to 10 Volts. Then by appropriate switching between "On Time"
duty cycle pulses, allow the same coil to be induced by the magnet gap
"spring back" magnetic field to augment the collapsing coil field?
Could you not recover useful energy? Would this modulating process
not cause fluctuations on the other magnet poles enough to take
advantage of more inducing fields for more wound coils?
