The principle of the electric motor

The principle of the electric motor

After Oersted’s discovery of the magnetic effect of an electric current the possibility of producing an electric motor occurred to a number of scientists. In particular, William Wollaston and Michael Faraday discussed the problem together at the Royal Institution in London. Wollaston unsuccessfully tried some experiments and then lost interest. Faraday, however, continued his investigations during 1821, and by the end of the year was able to show how continuous rotation could be obtained with a magnet and an electric current.
