How to Magnetize and Demagnetize a Screwdriver

When working with small screws it is very handy to have a magnetized screwdriver to pick up and hold the screws while they are installed. Be sure not to use your magnetic screwdriver near a computer hard drive!

Find the strongest magnet that you can. The magnet found on the back of an old audio speaker is perfect for this. Hold this magnet in one hand and the screwdriver in the other.

Pull the screwdriver across the magnet.

Touch the magnet to the base of the metal shaft of the screwdriver and pull the screwdriver until the tip reaches the magnet.

Repeat this several times to make the magnetic field stronger. Place some screws on a flat surface and test your new magnetic tool. The screws should stick to the screwdriver, making them easy to pick up and retrieve if dropped.

To demagnetize the screwdriver, do the same steps above, but in reverse. Place the tip of the metal shaft on the magnet and push the screwdriver until the magnet reaches the base of the shaft. Repeat several times and the screwdriver should no longer be able to pick up the screws.
