How do you add a magnet to a screwdriver?
If guided by a magnet, the iron molecule becomes ordered, resulting in magnetism, which is the magnetization effect. Magnetization is that the object never shows magnetism and has a certain magnetism. The fundamental reason is that the atomic magnetic moment in the material is arranged in the same direction. The existing device and method for magnetizing objects can magnetize the object through the action of an applied electromagnetic field. In addition, in interpersonal psychology, the phenomenon that a person's personality is magnetized and attracted by others is called "magnetization effect" in an image.
The magnetization effect is the effect of using a magnet to make the iron magnetic. Iron is magnetic, only because of the internal molecular structure messy, positive and negative two levels cancel each other, so it shows no magnetism.
The usual large permanent magnets are placed on the screwdriver head and magnetized for a period of time.
With a screwdriver to porcelain magnetization, or around a coil is energized by electromagnetic field to magnetic screwdriver;
