I found a model 99 Robins magnetic eraser. Designed to bulk erase magnetic tapes. Nixon should have had one.
Here is what one looks like.
Inside it is just a coil around an armature. Tried to demagnetize a pair of FK poly-neos. No apparent results. It did throw them across the room though.
Any ideas on how to re-purpose this into a "Magnet-Blaster"? Turbo or otherwise.
