How is the alternator connected to the engine?
A rubber belt connects the alternator to the engine crank pulley. As the engine rotates, the belt turns the rotor found in the stator. The rotor and stator are made from copper and electric steel. The rotor also has an electric current flowing through it, which induces a magnetic field.
