Hans Christian Ørsted (/ ˈ ɜːr s t ɛ d /; [5] Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; anglicized as Oersted; [note 1] 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields. This phenomenon is known as Oersted's law. He also discovered aluminium, a ...

In electromagnetism, Ørsted's law, also spelled Oersted's law, is the physical law stating that an electric current induces a magnetic field. [ 2 ] This was discovered on 21 April 1820 by Danish physicist Hans Christian Ørsted (1777–1851), [ 3 ] [ 4 ] when he noticed that the needle of a compass next to a wire carrying current turned so ...
The spacecraft was launched, on 23 February 1999 at 10:29:55 UTC, by a Delta II rocket, from the Vandenberg Air Force Base SLC-2W pad, as an auxiliary payload (primary payload was ARGOS and another auxiliary payload was SUNSAT; the auxiliary payload satellites were launched free of charge) into a near-Sun synchronous elliptical polar orbit, it had a perigee of 630 kilometres (390 mi), an ...
The oersted unit of magnetic induction is named for his contributions. 1820 – André-Marie Ampère , professor of mathematics at the École Polytechnique, demonstrates that parallel current-carrying wires experience magnetic force in a meeting of the French Academy of Science , exactly one week after Ørsted's announcement of his discovery ...
Cosmos: A Spacetime Odyssey is a 2014 American science documentary television series. [2] The show is a follow-up to the 1980 television series Cosmos: A Personal Voyage, which was presented by Carl Sagan on the Public Broadcasting Service and is considered a milestone for scientific documentaries.
1820: Hans Christian Ørsted discovers the relationship between electricity and magnetism in a very simple experiment. He demonstrates that a wire carrying a current was able to deflect a magnetized compass needle. 1831: Michael Faraday begins a series of experiments in which he discovers electromagnetic induction.
