The electromagnet is placed Electromagnetic Motor china between your poles of another magnet. When current from the voltage supply flows through the coil, a magnetic field is created 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 engine. As the wire rotates, the electric current changes directions.
