On the morning of Christmas day, 1821, Faraday called his wife
into his laboratory to witness, for the first time in the
history of man, the revolution of a magnet around an electric
current. The foundations of electromagnetics were laid and the
edifice was built by Faraday upon this foundation in the
fourteen succeeding years. In those years and from those
labors, the electro-motor, the motor generator, the electrical
utilization of water power, the electric car, electric
lighting, the telephone and telegraph, in short all that is
comprised in modern electrical machinery came actually or
potentially into being. The little rotating magnet which
Faraday showed his wife was, in fact, the first electric motor.
