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 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.
In 1852, Michael Faraday treated the magnetic field as a physical object, reasoning about lines of force. James Clerk Maxwell used Faraday's conceptualisation to help formulate his unification of electricity and magnetism in his field theory of electromagnetism.
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 ...
The first edition of the book, written in 1910, gives a detailed account of the aether theories and their development from René Descartes to Hendrik Lorentz and Albert Einstein, including the contributions of Hermann Minkowski. The volume focuses heavily on aether theories, Michael Faraday, and James Clerk Maxwell, devoting each one or more ...
1886: Heinrich Hertz succeeds in proving the existence of electromagnetic waves for the first time – now the groundwork for wireless telegraphy and radio broadcasting in physical science is laid. 1887: Unaware of Charles Sumner Tainter's experiments, German-American Emil Berliner has his phonograph patented. He used a disk instead of a ...
While building electromagnets, Henry discovered the electromagnetic phenomenon of self-inductance. He also discovered mutual inductance independently of Michael Faraday, though Faraday was the first to make the discovery and publish his results. [4] [5] [6] Henry developed the electromagnet into a practical device.
Michael Faraday (1791 – 1867), an English chemist and physicist, is credited with the discovery of electromagnetic induction, which formed the basis for exploiting electricity as a practical form of energy.
