    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.

  4. Faraday's law of induction - Wikipedia

    en.wikipedia.org/wiki/Faraday's_law_of_induction

    Electromagnetic induction was discovered independently by Michael Faraday in 1831 and Joseph Henry in 1832. [4] 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 ...

    Electromagnetic induction was discovered by Michael Faraday, published in 1831. [3] [4] It was discovered independently by Joseph Henry in 1832. [5] [6] In Faraday's first experimental demonstration, on August 29, 1831, [7] he wrapped two wires around opposite sides of an iron ring or "torus" (an arrangement similar to a modern toroidal ...

    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).
