Tips: Magnetizing and demagnetizing methods for screwdrivers

There are two ways of magnetizing the screwdriver.

The first method is to put a screwdriver and a permanent magnet together for a period of time. If you are in a hurry to use the screwdriver, rub it on the magnet in one direction for a few times, and then it can keep the magnetic property for a period of time. Or take a small magnet and attach it directly to the screwdriver.
Here is second option. If you don’t have a magnet in your hand, find a battery that can also be used for magnetizing. Use a wire to wind a coil around the screwdriver, and then electrify it with a 1.5V battery. Connect the two ends of the coil to the positive and negative poles for about a minute. That’s how magnetizers sold online work — electromagnetizing.

In some certain working conditions, a screwdriver with a magnetic head may not work well, and we need to demagnetize the screwdriver. There are 3 kinds of demagnetization methods for screwdriver.

The first method is heating up to make the internal magnetic field messes up and loses its magnetism.
Secondly, a few falls on the ground, similar to the first, also disrupt the internal magnetic field.
The third method is to use the demagnetizer, which can be simulated, that is, place two magnets repelling each other and put the screwdriver in the repellant space for a while. It is the opposite of magnetization.
