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.
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 ...
1803 – Thomas Young develops the Double-slit experiment and demonstrates the effect of interference. [15] 1806 – Alessandro Volta employs a voltaic pile to decompose potash and soda, showing that they are the oxides of the previously unknown metals potassium and sodium. These experiments were the beginning of electrochemistry.
In 1810, at Jena, Seebeck described the action of light on silver chloride sensitised paper (a technique used by Johann Ritter). [7] [8] He observed that the exposed chemical would sometimes take on an approximate, pale version of the color of the solar spectrum as projected from a prism to which it had been exposed, and also reported the action of light for a wavelengths beyond the violet end ...
Nov. 14—GROTON — Developers of Connecticut's first offshore wind farm are providing the University of Connecticut's Avery Point branch with a $1.25 million grant to fund a fisheries research ...
January 27 – John James Audubon (born 1785), naturalist and illustrator. February 18 – Carl Gustav Jakob Jacobi (born 1804), mathematician. March 9 – Hans Christian Ørsted (born 1777), physicist.
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 .
