Turbines consist of a series of fans, one in front of the other, which drive a shaft when they rotate. The shaft in turn drives a generator. Alternate fans always remain stationary. The position and shape of these fans direct the pressurized steam, or water, onto the rotating fans with the maximum possible force.
At the end of the shaft is a large magnet, which is surrounded by a coil of wire, inside the generator. As the magnetic core rotates, it causes an electric current to flow through the wire coil.
