The electromagnet is placed between your poles of another magnet. When current from the voltage source flows through the coil, a magnetic field is definitely 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 an electric current flows through a loop or coil of wire, positioned between the two poles of an electromagnet, the electromagnet exerts a magnetic force upon the wire and causes it to rotate. The rotation of the wire starts the motor. As the wire Electromagnetic Motor china rotates, the electric energy changes directions.
