The electromagnet is positioned between the poles of another magnet. When current from the voltage resource flows through the coil, a magnetic field is Electromagnetic Motor china usually created around the electromagnet. The poles of the magnet connect to the poles of the electromagnet, leading to the motor to 
carefully turn. … The more coils, the stronger the motor.
When an electric 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 motor. As the wire rotates, the electric energy changes directions.
