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