I thought the output coil voltage would be pretty low, like 5 volts or so.
The coil resistance has to be pretty low.

Yes -- but the coil inductance could raise its impedance
significantly, allowign higher voltages.

However -- with 5 turns and only 100 KHz, probably not that
significant. Of course the inductance is also a function of size (turns
diameter) as well as the number of turns.

The guys from Ameritherm did handhold the samples that they heated. That
was part of the demo; to show how the machine heated the end in the coil so
fast that the handheld end didn't get very hot.

Probably pretty low voltage, then.

Enjoy,
