RE: Magnetic Force with Tesla Coil?

Well, they do :) Like Dave Pierson said, the magnetic field is strong enough
to vibrate and induction heat ferrous metals, and bend the beam on an
oscilloscope into little loops. I have never seen a TC primary actually grab
pieces of iron, but I suspect this is because it's pulsed, the force doesn't
last long enough to overcome inertia and actually move things.

Here is a pic of the primary from my OLTC doing some induction heating with
1.2kW input and ~3500A peak current (note ripples in the water, show the
container is vibrating)
