Have you ever wondered where electricity comes from? You might be surprised to learn that it comes from magnets! In the early 1800s, Michael Faraday discovered electromagnetic induction, which is the scientific way of saying that if he moved a magnet through a loop of wire, the wire would become electrified. In 1882, Thomas Edison opened the first full-scale power plant in New York City. Edisons electric generator was a bigger version of Faradays basic experiment; a big magnet rotates around a wire to produce an electric current. Todays power plants are bigger and controlled by computers, but the basic process is still the same as it was nearly 120 years ago.
