Faraday’s Theory

Faraday wondered whether changing the magnetic field around a magnet could create a current in an unconnected wire. He tested this by switching an electromagnet on and off. Faraday saw that a current flowed first one way and then the other. He found that stronger electromagnets and bigger changes in the magnetic field produced bigger currents. Then Faraday tried moving a magnet in and out of a coil of wire. He created a steady current. This was the first generator.
