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 official position taken by the Wikimedia Foundation is that "faithful reproductions of two-dimensional public domain works of art are public domain".This photographic reproduction is therefore also considered to be in the public domain in the United States.
Copenhagen, in particular, acquired a new look, with buildings designed by Christian Frederik Hansen and Michael Gottlieb Bindesbøll. In relation to music, the Golden Age covers figures inspired by Danish romantic nationalism including J. P. E. Hartmann, Hans Christian Lumbye, Niels W. Gade and the ballet master August Bournonville.
The oersted (/ ˈ ɜːr s t ɛ d /,; [1] symbol Oe) is the coherent derived unit of the auxiliary magnetic field H in the centimetre–gram–second system of units (CGS). [2] It is equivalent to 1 dyne per maxwell .
Hans Christian Ørsted. Hans Christian Ørsted (14 August 1777 – 9 March 1851) was a Danish physicist and chemist, influenced by the thinking of Immanuel Kant. He is best known for discovering the relationship between electricity and magnetism known as electromagnetism. From 1806, Ørsted was a professor at the University of Copenhagen.
In 1827, Friedrich Wöhler refined a process discovered by Hans Christian Ørsted, a Danish chemist, who first produced impure aluminium in 1825. With the newly made Al metal, he established the specific gravity of aluminium in 1845.
He was the brother of noted physicist Hans Christian Ørsted (1777–1851), and uncle of the botanist Anders Sandøe Ørsted (1816–1872). He was married to Sophie Ørsted née Oehlenschläger (1782–1818) and was the brother-in-law of Adam Oehlenschläger .
