APG electromagnets can be divided into two types: DC electromagnets and AC electromagnets.

If electromagnets are classified according to their purpose, they can be mainly divided into the following five types:

(1) Traction electromagnet - mainly used for pulling mechanical devices, opening or closing various valves, to perform automatic control tasks.

(2) Lifting electromagnet - used as a lifting device to lift ferromagnetic materials such as steel ingots, steel, iron sand, etc.

(3) Brake electromagnet - mainly used for braking electric motors to achieve accurate parking.

(4) The electromagnetic system of automatic appliances, such as electromagnetic relays and contactors, electromagnetic releases for automatic switches, and operating electromagnets.

(5) Electromagnets for other purposes, such as electromagnetic suction cups for grinding machines and electromagnetic vibrators.
