Got a screw loose?
Don't worry. We all do. This handy tutorial will keep any screw secured to any screwdriver.
This method of magnetization uses a copper wire and a car battery. This is much more effective than simply rubbing a screwdriver with a magnet. It also holds the magnetic charge for a longer time.
Careful. Car batteries are pretty fierce. Fool around with the arc, and you might find yourself grounding the 12 volts of electric current. And there is a risk of frying your battery cells if you go too far.

This is very true ,Ilearned this procedure about 45 years ago And forgot it.Thanks for bringing it back to my memory bank.I worked in upholstery and use to use a tack hammer and used to magnetize it this way.Thank you,Herman
Pretty cool. I knew how to magnitize it by rubbing it with a magnet, but creating an electro-magnet this way is a pretty useful substitue when you don't have a spare magnet around...
thank you for this.
how long does it last for?
long enough to get the job done i suppose.i mean really,in 5 minutes you could magnetize every screwdriver,drill bit,allen wrench and so forth that you own.
as long as you don't tap or drop the skruedriver it will hold a long time, and longer then using a non electricmagnet :-)
oooooooooohhhhhh
