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 chemist and physicist who discovered that electric currents create magnetic fields. This phenomenon is known as Oersted's law. He also discovered aluminium, a ...
H. C. Ørsted Power Station (Danish: H. C. Ørstedværket) is a natural gas fired combined heat and power station located at Enghave Brygge, Sydhavnen in Copenhagen, Denmark. It is owned and operated by Ørsted. It is named after the Danish physicist Hans Christian Ørsted, the discoverer of electromagnetism.
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 ...
1820 – Hans Christian Ørsted, Danish physicist and chemist, develops an experiment in which he notices a compass needle is deflected from magnetic north when an electric current from the battery he was using was switched on and off, convincing him that magnetic fields radiate from all sides of a live wire just as light and heat do ...
Hans Christian Ørsted's discovery of the magnetic effect of electric currents in 1820 was immediately recognised as an important advance, although he left further work on electromagnetism to others. André-Marie Ampère quickly repeated Ørsted's experiment, and formulated them mathematically (which became Ampère's law) . Ørsted also ...
Hans Christian Ørsted One name stands out above all others among those who contributed to science during the Danish Golden Age, that of Hans Christian Ørsted , the prominent physicist and chemist known for observing that electric currents induce magnetic fields , an important aspect of electromagnetism .

An early D'Arsonval galvanometer showing magnet and rotating coil. A galvanometer is an electromechanical measuring instrument for electric current.Early galvanometers were uncalibrated, but improved versions, called ammeters, were calibrated and could measure the flow of current more precisely.
