The electromagnet is positioned between the poles of another magnet. When current from the voltage supply flows Electromagnetic Motor china through the coil, a magnetic field can be produced 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 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 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.
