Hans Christian Ørsted was a Danish physicist and chemist who discovered that electric current in a wire can deflect a magnetized compass needle, a phenomenon the importance of which was rapidly recognized and which inspired the development of electromagnetic theory.

Hans Christian Ørsted FRSE (/ ˈ ɜːr s t ɛ d /, Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; often rendered Oersted in English; 14 August 1777 – 9 March 1851) was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and ...
Jul 1, 2008 · During a lecture demonstration, on April 21, 1820, while setting up his apparatus, Oersted noticed that when he turned on an electric current by connecting the wire to both ends of the battery, a compass needle held nearby deflected away from magnetic north, where it normally pointed.
In 1820, Hans Christian Oersted performed an important experiment which showed that there was a connection between electricity and magnetism. When a current was switched on through a wire, it made a compass needle turn so that it was at right angles to the wire.
Oersted, unit of magnetic-field strength in the centimetre-gram-second system of physical units. Named for the 19th-century Danish physicist Hans Christian Ørsted, it is defined as the intensity of a magnetic field in a vacuum in which a unit magnetic pole (one that repels a similar pole at a.
In electromagnetism, Ørsted's law, also spelled Oersted's law, is the physical law stating that an electric current creates 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 ...
