The electromagnet is placed between the poles of another magnet. When current from the voltage source flows through the coil, a magnetic field is usually 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 stronger the motor.

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