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