The electromagnet is positioned between your poles of another magnet. When current from the voltage source flows through the coil, a magnetic field is Electromagnetic Motor china certainly created around the electromagnet. The poles of the magnet interact with the poles of the electromagnet, causing the motor 
to carefully turn. … The more coils, the stronger the motor.
When a power current flows through a loop or coil of wire, positioned between the 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 motor. As the wire rotates, the electric current changes directions.
