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 .
For Faraday's first law, M, F, v are constants; thus, the larger the value of Q, the larger m will be. For Faraday's second law, Q, F, v are constants; thus, the larger the value of (equivalent weight), the larger m will be. In the simple case of constant-current electrolysis, Q = It, leading to
Michael Faraday. The Faraday paradox or Faraday's paradox is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes: Faraday's law appears to predict that there will be zero electromotive force (EMF) but there is a non-zero EMF.

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 ...
The Faraday paradox was a once inexplicable aspect of the reaction between nitric acid and steel. Around 1830, the English scientist Michael Faraday found that diluted nitric acid would attack steel, but concentrated nitric acid would not. [1] The attempt to explain this discovery led to advances in electrochemistry.
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 ...
Mond's vision for the laboratory included its association with the Royal Institution, which had an association with Humphry Davy and Michael Faraday, whose names the laboratory commemorates. The building was designed to accommodate independent investigators, and preference was given to those who had already demonstrated significant ...
