The AC unit I use is a VHS tape bulk eraser. It's pretty strong and has
a limited working time--maybe 2-3 minutes before the thermal cutout
interrupts. Let it cool for a few minutes and get back to work.
How strong a DC erase? I suppose that one of these magnets could well
lift a 100 lbs. Scary strong.
