Magnetic OU principle, You should really take a look at this !

Butch,

I hadn't thought of that yet... indeed, it may be intended to make you look bad.
Not that it works, 'cause everyone who understands the concept will see that
the coil is wrong, and will know that it should be a normal "horizontal" coil.

Aside from that, do you really think such a setup would produce more
energy at that coil than it would need to cause the movement of the magnet
which causes the induction of that output?

Koen,
Yes I do if it was operated at resonance.

The work from expansion of the elements during approach would have to be recovered for closing them.
See attached drawing.
Thanks,

I will have it up in next hour. The ratio of pull in force to pull out force with the test fixture modified is amazing and we still have VERY many more ways to increase it.
Hang on,

I believe the work ratio can be increased as much as 4 times what you see in this video!
Enjoy,
