A diagram of Faraday's iron ring-coil apparatus Built in 1831, the Faraday disc was the first electric generator. The horseshoe-shaped magnet (A) created a magnetic field through the disc (D) . When the disc was turned, this induced an electric current radially outward from the centre toward the rim.
The operating principle of electromagnetic generators was discovered in the years of 1831–1832 by Michael Faraday. The principle, later called Faraday's law, is that an electromotive force is generated in an electrical conductor which encircles a varying magnetic flux.
The word was coined in 1831 by Michael Faraday, who utilized his invention toward making many discoveries in electricity (Faraday discovered electrical induction) and magnetism. [ 15 ] [ 16 ] The original "dynamo principle" of Werner von Siemens referred only to the direct current generators which use exclusively the self-excitation (self ...
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. His discovery paved the way for the development of generators, induction motors, transformers, and most other electrical machines.
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 ...

Faraday disc. The first homopolar generator was developed by Michael Faraday during his experiments in 1831. It is frequently called the Faraday disc or Faraday wheel in his honor. It was the beginning of modern dynamos — that is, electrical generators which operate using a magnetic field.
