Both the rotor and the stator of an AC generator belong to electromagnets. When current is passed through the stator coil, it creates a rotating magnetic field within the stator coil. The conductors on the rotor are pushed by the electromagnetic induction force, thereby rotating the rotor. This rotor is like the engine of a car, converting mechanical energy into electrical energy.
The DC generator uses a rotating conductor to generate an electromotive force in a magnetic field. According to Faraday's law, a moving conductor perceives a magnetic field and creates a potential difference on its two sides. Therefore, when the conductor rotates, the potential difference will change, resulting in a current.
