The electromagnet is placed between your poles of another magnet. When current from 
the voltage source flows through the coil, a Electromagnetic Motor china magnetic field is usually produced around the electromagnet. The poles of the magnet interact with the poles of the electromagnet, leading to 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 upon 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.
