  Michael Faraday - MSN Encarta
Faraday was born on September 22, 1791, in Newington, Surrey, England.
Faraday was the recipient of many scientific honors, including the Royal and Rumford medals of the Royal Society; he was also offered the presidency of the society but declined the honor.
In experimenting with magnetism, Faraday made two discoveries of great importance; one was the existence of diamagnetism, and the other was the fact that a magnetic field has the power to rotate the plane of polarized light passing through certain types of glass.

 Michael Faraday
Michael Faraday, the discoverer of electro-magnetic induction, electro-magnetic rotations, the magneto-optical effect, diamagnetism, field theory and much else besides, was born in Newington Butts (the area of London now known as the Elephant and Castle) on 22 September 1791.
In 1805 at the age of fourteen Faraday was apprenticed as a bookbinder to George Riebau of Blandford Street.
Faraday was part of this effort and on 3 and 4 September 1821 in his basement laboratory at the Royal Institution, he undertook a set of experiments which culminated in his discovery of electro-magnetic rotation - the principle behind the electric motor.

 Faraday's Law of Induction   (Site not responding. Last check: 2007-11-01)
Faraday discovered that, whenever the magnetic field about an electromagnet was made to grow and collapse by closing and opening the electric circuit of which it was a part, an electric current could be detected in a separate conductor nearby.
Faraday visualized a magnetic field as composed of many lines of induction, along which a small magnetic compass would point.
This relationship, known as Faraday's law of induction, states that the magnitude of the emf induced in a circuit is proportional to the rate of change of the magnetic flux that cuts across the circuit.
