how to magnetize a hand tool?

A screwdriver or socket is a common tool for driving screws. For the convenience of fixing the screws, the screwdriver or bit is magnetic. How did this magnetism come about?

Magnetism is charged from the magnetizer. Of course, magnetism can be recharged, and vice versa, magnetism can be withdrawn.

The working method is very simple, there are positive and negative poles on the magnetizer. When magnetizing, insert a screwdriver into the positive pole and swipe left and right several times. When demagnetizing, insert a screwdriver into the negative pole and scratch it on the left and right.

The magnetization process of a screwdriver is a phenomenon in which the head of a screwdriver is magnetized. Magnetization refers to the phenomenon in which, under the influence of a magnetic field, the orientation of magnetic moments in a material tends to be constant, exhibiting a certain degree of magnetism, and then causing the original non-magnetic substances to acquire magnetism.

The magnetization effect depends on the material being magnetized. Good steel can be magnetized faster and has a large magnetic field. On the contrary, the magnetic effect of bad steel is much worse. There are also some materials that cannot be magnetized, such as gold, silver, copper, aluminum, etc.

The one in the picture is a relatively simple magnetizer that is suitable for a relatively single or small number of items. For example, when a factory mass-produces magnetizing devices, a relatively large magnetizing device is usually used, and several products can work at the same time.
