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 .
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).
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.
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
1831 – Michael Faraday began experiments leading to his discovery of the law of electromagnetic induction, though the discovery may have been anticipated by the work of Francesco Zantedeschi. His breakthrough came when he wrapped two insulated coils of wire around a massive iron ring, bolted to a chair, and found that upon passing a current ...
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 ...

1820: Michael Faraday and James Stoddart discover alloying iron with chromium produces a stainless steel resistant to oxidising elements . 1821: Thomas Johann Seebeck is the first to observe a property of semiconductors. [citation needed] 1824: Carnot: described the Carnot cycle, the idealized heat engine.
