Generating Electricity
In the first half of the 19th century, Micheal Faraday found that if a magnet was made to move quickly past a wire, a current of electricity was generated by the wire. This discovery led to the development of electrical generators, in which a large magnet is made to spin around inside a larger coil of wire and produce electricity. In many power stations the magnet is attached to a turbine, which is made to spin by driving steam over it.
