H. C. Oersted found that electricity can produce magnetic fields, leading to the electromagnet, the telegraph, and the electric motor. Michael Faraday showed that moving magnets induce electricity—the principle behind most electric-power generation. James Clerk Maxwell described the links between electricity and magnetism in four elegant equations.
