For sale is a Electro-Matic WAY Demagnetizer. The handle on the bottom seems to have adapted it to be dragged on top of flat surfaces, like machine ways, to demagnetize them? Remove the handle and you have a regular demagnetizer. I plugged it in and it works, if I put it against steel surfaces, I feel a buzz. The cable is frayed and if I were you, I would replace it, however, it does not seem to project any open copper strands. 115 volts.
