Fascinating -- I didn't know there were AC and DC magnetic fields. How strong is "very strong", and would the library device I mentioned count toward "an AC erase"? Should I assume that just doing an AC erase would be insufficient?
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.
