Hi All,

  In regards to the person inside a faraday cage above a tesla coil... It
seems that the induced magnetic fields would operate at the same high
frequencies as the coil itself. Then the induced currents within the person
would also be high frequency, and have a tendency to pass over the skin...

The magnetic fields at the top of the coil are not that
extraordinary.  Maybe 10's of amps.  Greg had an electronic oscilloscope
with him that was not harmed.  I would guess if people can stand the
magnetics of MRI machines, they can stand top of Tesla coils easily.  The
currents in the coil could induce some voltage around one's body.  But the
resistance of the body is so high the current would be nil.

Cheers,
