The electromagnet is placed between the poles of another magnet. When current from the voltage resource flows through the coil, a magnetic field is definitely created around the electromagnet. The poles of the magnet interact with the poles of the electromagnet, causing the motor to carefully turn. ... The more coils, the more powerful the motor.
When a power current flows through a loop or coil of wire, placed between the two poles of an electromagnet, the electromagnet exerts a magnetic force on the wire and causes it to rotate. The 
rotation of the wire starts the Electromagnetic Motor china electric motor. As the wire rotates, the electric current changes directions.
