Never lose a screw again. Magnetize your screwdrivers to allow them to grab small screws. Demagnetize your screwdrivers to safely work on sensitive electronics. Alternate magnetizations as many times as your heart desires! To magnetize your screwdriver, insert the end of it into the "Magnetize" hole. To demagnetize your screwdriver, repeatedly pull the entire length of the screwdriver through the "Demagnetize" hole.
