The electromagnet is positioned between your poles of another magnet. When current from the voltage supply flows through the coil, a magnetic field can be created 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 starts the electric motor. As the wire Electromagnetic Motor china rotates, the electric current changes directions.
