Michael Faraday bust – Burlington House. A bronze bust representing Michael Faraday, English scientist whose studies greatly contributed to the fields of electromagnetism and electrochemistry. The bust was presented to the Chemical Society by James Emerson Reynolds (1844–1920), president of the Chemical Society from 1901 to 1903: [10] [11] [12]
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.
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]
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.
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 (August 29, 1831), he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal transformer).
Michael Faraday developed the concept of lines of force to describe electric and magnetic phenomena. [13] In 1831, he writes [13] By magnetic curves, I mean the lines of magnetic forces, however modified by the juxtaposition of poles, which would be depicted by iron filings; or those to ·which a very small magnetic needle would form a tangent."
