Michael faraday (1791September 22 ~1August 25, 867) is a British physicist, chemist and a famous self-taught scientist. Faraday first discovered electromagnetic induction on1831/kloc-0+017, and then obtained the method of generating alternating current. 183 1 year1year1October 28th Faraday invented the disc generator, which is the first generator created by human beings. Because of his great contribution to electromagnetism, he is called "the father of electricity" and "the father of alternating current".

The discovery of electromagnetic induction is one of the greatest achievements in electromagnetism. It not only reveals the internal relationship between electricity and magnetism, but also lays the experimental foundation for the mutual transformation between electricity and magnetism, and opens the way for human beings to obtain huge and cheap electric energy, which has important practical significance. The discovery of electromagnetic induction marks the arrival of a major industrial and technological revolution.
