A series of free Science Lessons for 7th Grade and 8th Grade, KS3 and Checkpoint Science in preparation for GCSE and IGCSE Science.

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.
