You could try using a degaussing coil, it's used
un-magnetize picture tubes, might work on small parts.
Find a junked color TV (bigger the better) and take
the degaussing coil out of it. Twist the coil to loop
it into a small 5" or so circle, add a power cord, and
wrap the stacked layers of the coil in tape. Don't
leave it plugged in for more than a couple seconds
though! It's not intended to be powered for very long.
If you can locate one, try a videotape degausser. Radio Shack used
to have a very handy unit that was very useful for degaussing
I've also heard of people using old DC focus coils from early 50's
TVs hooked to line current. Unless you had a very extensive hellbox,
however, one of those would be difficult to find. I wonder if an old
DC choke (in the henrys range) could be used if one removed the "I"
side of the core and left the "E" sections in place.
