Michael Faraday (/ ˈ f ær ə d eɪ,-d i /; 22 September 1791 – 25 August 1867) was an English physicist and chemist who contributed to the study of electromagnetism and electrochemistry. His main discoveries include the principles underlying electromagnetic induction , diamagnetism and electrolysis .
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 dark space – The dark area in front of a cathode in a vacuum tube; Homopolar generator, aka Faraday disc or Faraday wheel; Faraday effect – Physical magneto-optical phenomenon Faraday filter, aka atomic line filter – Optical band-pass filter used in the physical sciences
A close-up image of a candle showing the wick and the various parts of the flame; Michael Faraday lectured on "The Chemical History of a Candle".The Royal Institution's Christmas Lectures were first held in 1825, [2] and have continued on an annual basis since then except for four years during the Second World War.

1831: Electromagnetic induction was discovered by Michael Faraday in England in 1831, and independently about the same time by Joseph Henry in the U.S. [37] 1831: Chloroform – Samuel Guthrie in the United States (July 1831), and a few months later Eugène Soubeiran (France) and Justus von Liebig (Germany), all of them using variations of the ...
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. The experiment which led Faraday to the discovery of electromagnetic induction was made as follows: He constructed what is now and was then termed an induction coil, the primary and secondary wires of which were wound on a wooden bobbin, side by side, and insulated from one another. In the circuit of the primary wire he placed ...
Joseph Henry (December 17, 1797 [1] [2] – May 13, 1878) was an American physicist and inventor who served as the first secretary of the Smithsonian Institution.He was the secretary for the National Institute for the Promotion of Science, a precursor of the Smithsonian Institution. [3]
