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 100�S, 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
