Magnet divided natural and artificial magnets magnet. Artificial magnets are divided into two types: one is a permanent magnet; the other is an electromagnet. The difference is that the permanent magnet is made of magnetic material (e.g. magnetic alloys, ceramic magnets, etc.) made. The electromagnet is wound around the outer core of the iron core, and magnetic current is generated by the direct current, and the magnetic force disappears after the power is turned off.
