What is Screwdriver Magnetizer / Demagnetizer
Quickly and easily magnetizes small tools and screwdrivers so they attract screws or nuts for easy starting and removing. Insert a screwdriver into the hole, pull it out and it’s magnetized! Perfect for do-it-yourselfers, mechanics and electricians.
To pick up and hold screws, just insert the screwdriver tip into the "+" marked end. The tip is magnetized and screws are easier to handle. While repairing electric appliances and electronic components, simply insert the screwdriver tip into the "-" marked end to instantly demagnetize the tip.
