How to Magnetize a Screwdriver: 10 Steps (with Pictures) – wikiHow

To magnetize a screwdriver with a battery, start by stripping the insulation from the ends of a piece of wire. Then, wrap the wire around your screwdriver 10-20 times. Once the wire is around the screwdriver, attach the ends of the wire to a 6V or 9V battery. You should then wait 30-60 seconds for the current flowing through the wire to create a magnetic field before you disconnect the battery and use your newly magnetized screwdriver. Alternatively, you can get a strong bar magnet and drag it in the same direction along every side of your screwdriver to magnetize it.
