|The Precision Magnetizer and Demagnetizer transforms standard screwdrivers, tweezers and tool bits into powerful magnetic pickups. This dual-sized device can magnetize screwdrivers for installing small screws in jewelry, or demagnetize a set of tweezers for working with sensitive electronics. In addition, the innovative step design allows you to control the level of magnetism that is imposed upon your tools.|
There is a powerful magnet in the magnetize side that will magnetize the tool as it is passed through. There is another magnet on the de-magnetize side but with the opposite magnetic field that will de-magnetize the tool.
