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 .
1831: Michael Faraday begins a series of experiments in which he discovers electromagnetic induction. The relation was mathematically modeled by Faraday's law, which subsequently becomes one of the four Maxwell equations. Faraday proposes that electromagnetic forces extended into the empty space around the conductor, but does not complete his ...
Michael Faraday developed the concept of lines of force to describe electric and magnetic phenomena. [14] In 1831, he writes [14] 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."
Glazed frame, containing "Delineation of Lines of Magnetic Force by Iron filings" prepared by Michael Faraday. Michael Faraday was the first who suggested that action at a distance was inadequate as an account of electric and magnetic forces, even in the form of a (mathematical) potential field.
August Karolus and the company Telefunken put on the "fifth Great German Radio Exhibition Berlin 1928" the prototype of a television receiver, with an image size of 8 cm × 10 cm and a resolution of about 10,000 pixels, a much better picture quality than previous devices.

Michael Faraday was the first to propose that light should be interpreted as a field, much like the magnetic fields on which he had been working. [1] The term light field was coined by Andrey Gershun in a classic 1936 paper on the radiometric properties of light in three-dimensional space.
The unit of capacitance is the farad, named after Michael Faraday, and given the symbol F: one farad is the capacitance that develops a potential difference of one volt when it stores a charge of one coulomb. A capacitor connected to a voltage supply initially causes a current as it accumulates charge; this current will however decay in time as ...
