I remember seeing a mechanic magnetize a screwdriver when I was a kid. I thought he hooked it up to a 12V battery with wire. I tried that and got nothing. Anybody help me out on this or do I remember something that never happened and is unpossible?

You can lightly magnatize things by simply rubbing a magnet down the item 10-15 times going the same direction each time.

If you coil wire around the shank of the screwdriver and then hook each end to a battery, you can have an electromagnet. Won't permanently magnetize it though.

Leave it attached to a magnet over night.

I use a magnetic screwdriver one time on a screw, and that screw becomes magnetized itself. Now it will stick itself to non magnetic screwdrivers.

I imagine that would work for the driver too, being as I have no idea how my screwdriver became magnetized in the first place.

I used to do this with a wire wrapped cardboard tube, 120v receptacle and a piece of aluminum foil as a fuse.

It will if you manage to get enough amp-turns.
