Ideal for both magnetizing and demagnetizing metal or steel tools, especially screwdrivers. Simply place the metal or steel portion of the tool you would like to magnetize into the "+" slot and turn it clockwise several times. Once you are ready to demagnetize your tool simply place the steel or metal portion into the "-" slot and rotate it several times. This ability allows you to make tasks, like grabbing small metal fasteners, easier while still allowing you to re-use the same tool (once demagnetized) on electronics. The compact design of the Magnetizer / Demagnetizer makes it easy to store and transport.
