The electromagnet is positioned between the poles of another magnet. When current from the voltage resource flows through the coil, a Electromagnetic Motor magnetic field is produced around the electromagnet. The poles of the magnet interact with 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 your two poles of an electromagnet, the electromagnet exerts a magnetic force upon the wire and causes it to rotate. The rotation of the wire begins the motor. As the wire rotates, the electric current changes directions.
