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 .
The Chemical History of a Candle was the title of a series of six lectures on the chemistry and physics of flames given by Michael Faraday at the Royal Institution in 1848, as part of the series of Christmas lectures for young people founded by Faraday in 1825 and still given there every year.

Michael Faraday. The experiment which led Faraday to the discovery of electromagnetic induction was made as follows: He constructed what is now and was then termed an induction coil, the primary and secondary wires of which were wound on a wooden bobbin, side by side, and insulated from one another. In the circuit of the primary wire he placed ...
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]
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."
Michael Faraday presenting his experiments with electromagnetism at a Christmas Lecture, 1856. This episode provides an overview of the nature of electromagnetism, as discovered through the work of Michael Faraday. Tyson explains how the idea of another force of nature, similar to gravitational forces, had been postulated by Isaac Newton before.
In 1846 Michael Faraday speculated that light was a wave disturbance in a "force field". [ 22 ] Expanding upon a series of experiments by Felix Savary, [ 23 ] [ 24 ] [ 25 ] between 1842 and 1850 Joseph Henry performed experiments detecting inductive magnetic effects over a distance of 200 feet (61 m).
