Faraday's discovery of electromagnetic induction occurred in 1831. He discovered the two fundamental laws of electrolysis. Faraday also established the principle that different dielectric substances have different specific inductive capacities. In 1821 Faraday also designed an electric motor.

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.

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.

His writings include Chemical Manipulation (1827), Experimental Researches in Electricity (1844-55), and Experimental Researches in Chemistry and Physics (1859).

Faradays Laws of Electrolysis:

The amount of chemical action produced by an electrical current in an electrolyte is proportional to the amount of electricity passing through the electrolyte. The amount of a substance deposited from an electrolyte by the action of a current is proportional to the chemical equivalent weight of the substance.

The Unit of electric capacitance, the farad, F, a derived Unit is named in his honour.

The farad is the SI unit of electric capacitance. One farad is defined as the ability to store one coulomb of charge per volt of potential difference between the two conductors.
