Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English chemist and physicist who contributed to the study of electrochemistry and electromagnetism. His main discoveries include the principles underlying electromagnetic induction , diamagnetism , and electrolysis .
Portrait of Michael Faraday is an oil on canvas portrait painting by the British artist Thomas Phillips, from 1841-1842. It depicts the English scientist Michael Faraday. [1] [2] [3] Faraday was a leading physicist and chemist who began his career as an assistant to Humphry Davy. Phillips was a noted portraitist of the Regency and early ...
The Chemical History of a Candle was the title of a series of six lectures on the chemistry and physics of flames given by Michael Faraday at the Royal Institution in 1848, as part of the series of Christmas lectures for young people founded by Faraday in 1825 and still given there every year.
Faraday later used the principle to construct the electric dynamo, the ancestor of modern power generators. He went on to investigate the fundamental nature of electricity, concluding in 1839 that, contrary to opinions at the time, only a single "electricity" exists, and the changing values of quantity and intensity (voltage and charge) would ...

Michael Faraday developed the laws of electrolysis. 1833: Michael Faraday invented the thermistor: 1833: English physicist Samuel Hunter Christie invented the Wheatstone bridge (It is named after Charles Wheatstone who popularized it). 1836: Irish priest (and later scientist) Nicholas Callan invented the transformer in Ireland. 1837
Michael Faraday holding a piece of glass of the type he used to demonstrate the effect of magnetism on polarization of light, c. 1857.. By 1845, it was known through the work of Augustin-Jean Fresnel, Étienne-Louis Malus, and others that different materials are able to modify the direction of polarization of light when appropriately oriented, [4] making polarized light a very powerful tool to ...
