guys!

It is possible to induce electric current into the human body, it is
done for therapeutic reasons, and the current induced appear to occeur
in the nerves.

I have seen one such machine at work, at the Electricity Museum, and a
one turn coil in proximity of the 17 turns work coil revealed that the
pulse length is 100µS, the current producing it is in the thousands of
amperes, and the flux intensity is more than 2 Tesla.

Funny to work with: Place the coil where the halo of a saint would be,
fire the coil, and you get funny looking, involuntary jaw movements. One
of the office secretaries bit her tongue!. What a laugh :-).

It is a disk launcher, really.

Cheers, Finn Hammer
