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 .
Georgia Piedmont Technical College (GPTC) is a public community college based in Clarkston, Georgia. It is part of the Technical College System of Georgia (TCSG) and provides education for a three-county service area, mostly in the metro Atlanta area. The school's service area includes Dekalb, Rockdale, and Newton counties. [1]
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 ...
Piedmont Technical College is a public community college with its main campus in Greenwood, South Carolina. It serves seven counties in the Lakelands region of South Carolina. Six additional County Centers also serve students in Abbeville County, Edgefield County, Laurens County, McCormick County, Newberry County, and Saluda County.
During the 20th century, the maximum energy product of commercially available magnetic materials rose from around 1 MGOe (e.g. in KS Steel) to over 50 MGOe (in neodymium magnets). [4] Other important permanent magnet properties include the remanence ( B r ) and coercivity ( H c ); these quantities are also determined from the saturation loop ...
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 ...
Giorgi later identified the need for an electrical base unit, for which the unit of electric current was chosen for SI. Another three base units (for temperature, amount of substance, and luminous intensity) were added later. [1] The early metric systems defined a unit of weight as a base unit, while the SI defines an analogous unit of mass.
