The electromagnet is placed between the poles of another magnet. When current from the voltage source flows through the coil, a magnetic field is definitely 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 stronger 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 on the wire and causes it to rotate. The rotation of the wire 
Electromagnetic Motor china begins the electric motor. As the wire rotates, the electric current changes directions.
