Joseph Henry Discovers Electromagnetic Induction
Close
PrintJoseph Henry uses his electromagnet and a battery to induce an electric current measurable by a galvanometer, and to create sparks. He publishes his results in Silliman's American Journal of Science in July, 1832, shortly after British scientist Michael Faraday published similar results in another scientific journal. In 1846, Henry would become the first Secretary of the Smithsonian Institution.
