Event: IoP History Group Celebrates 200 Years Of Electromagnetism
On 16 September 2020, The Institute of Physics History Group is organising a one-day seminar to celebrate the publication of Oersted's seminal paper on electromagnetism. In July 1820, Hans Christian Oersted (1777-1851) of the University of Copenhagen published a four-page text “Experiments on the effect of the electric conflict on the magnetic needle”. He had discovered that a wire carrying an electric current generated by a Voltaic pile affected the orientation of a nearby compass needle and in particular that the effect circulated outside the wire in the plane perpendicular to it. Within months, André-Marie Ampère (1775-1836) had extended Oersted’s work by experiment and mathematics. Ampère published his magnum opus on electrodynamics in 1826/1827, establishing himself, according to…
