    Faraday was the first to publish the results of his experiments. [5] [6] Faraday's 1831 demonstration [7] Faraday's notebook on August 29, 1831 [8] describes an experimental demonstration of electromagnetic induction (see figure) [9] that wraps two wires around opposite sides of an iron ring (like a modern toroidal transformer).

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic or magnetic induction is the production of an electromotive force (emf) across an electrical conductor in a changing magnetic field. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction .

    Electromagnetic rotation experiment of Faraday, 1821, the first demonstration of the conversion of electrical energy into motion [48] In 1821, soon after the Danish physicist and chemist Hans Christian Ørsted discovered the phenomenon of electromagnetism, Davy and William Hyde Wollaston tried, but failed, to design an electric motor.
