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.
The discovery of electromagnetic induction was made almost simultaneously, although independently, by Michael Faraday, who was first to make the discovery in 1831, and Joseph Henry in 1832. [77] [78] Henry's discovery of self-induction and his work on spiral conductors using a copper coil were made public in 1835, just before those of Faraday.
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]
Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...
English physicist Michael Faraday published the law of induction (Joseph Henry developed the same law independently). 1831: American scientist Joseph Henry in the United States developed a prototype DC motor. 1832: French instrument maker Hippolyte Pixii in France developed a prototype DC generator. 1833: Michael Faraday developed the laws of ...
Electromagnetic induction was discovered by Michael Faraday, published in 1831. [3] [4] It was discovered independently by Joseph Henry in 1832. [5] [6] In Faraday's first experimental demonstration, on August 29, 1831, [7] he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal ...
Volume II, containing correspondence with Johann Wilhelm Ritter and numerous others, including Michael Faraday and Carl Friedrich Gauss. A significant number of Ørsted's papers were made available in English for the first time in a compilation published in 1998: [26] Ørsted, H. C. (1998). Jelved, K.; Jackson, A. D.; Knudsen, O. (eds.).
Before 1830, Johann Michael Ekling: Austrian, mechanic; constructed an electric motor according to the plans of Austrian physicist Andreas von Baumgartner. [17] 1831 Michael Faraday: British, scientist; discovered and investigated induction law in terms of electric current generation in a varying magnetic field. [3] [5] [6] [18] 1831, Joseph Henry
