(1791-1867) an English scientist. His family was very poor and he had to teach himself about science, before becoming the assistant of Humphrey Davy. His early work was in chemistry, but his most famous work was in physics. He discovered electromagnetic induction, the condition under which a magnet can produce electricity. This led to the development of the electric dynamo and motor. His discoveries in the field of electrolysis are still known as Faraday's Laws.
