The electromagnet is positioned between the poles of another magnet. When current from the voltage resource flows through the coil, a magnetic field can be Electromagnetic Motor china created around the electromagnet. The poles of the magnet connect to the poles of the electromagnet, causing the motor to turn. … The more coils, the more powerful the motor.

When a power current flows through a loop or coil of wire, positioned between the two poles of an electromagnet, the electromagnet exerts a magnetic force on the wire and causes it to rotate. The rotation of the wire begins the electric motor. As the wire rotates, the electric current changes directions.
