This magnetizer-demagnetizer enables rapid control over the magnetic properties of screwdrivers, nut drivers, and small steel hand tools. To apply a charge for fastener retention, the tool is inserted into the positive (+) chamber, while the stepped negative (-) chamber removes magnetism through a series of passes. If residual magnetism remains after the initial pass, the multi-step configuration allows for additional cycles on higher levels to neutralize the tool completely.
