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 (/ ˈ ɜːr s t ɛ d /; [5] Danish: [ˈhænˀs ˈkʰʁestjæn ˈɶɐ̯steð] ⓘ; often rendered Oersted in English; [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.
The Avedøre Power Station (Danish: Avedøreværket) is a combined heat and power station, located in Avedøre, Denmark, just south of Copenhagen, and is owned by Ørsted A/S. Avedøre Power Plant is a high-technology facility and one of the world's most efficient of its kind, being able to utilize as much as 94% of the energy in the fuel and convert 49% of the fuel energy into electricity.

There are 7 base units and 22 derived units [1] (excluding compound units). These units are used both in science and in commerce. Two of the base SI units and 17 of the derived units are named after scientists. [2] 28 non-SI units are named after scientists. By this convention, their names are immortalised.
The oersted (Oe) is a unit of magnetic field strength equal to 1 dyn 1/2 ⋅cm −1, corresponding to ~ 79.577 47 A/m. The maxwell (Mx) is a unit of magnetic flux , corresponding to 10 nWb . [ 4 ]
The gauss is the unit of magnetic flux density B in the system of Gaussian units and is equal to Mx/cm 2 or g/Bi/s 2, while the oersted is the unit of H-field. One tesla (T) corresponds to 10 4 gauss, and one ampere (A) per metre corresponds to 4π × 10 −3 oersted.
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 ...
Coercivity is usually measured in oersted or ampere/meter units and is denoted H C. An analogous property in electrical engineering and materials science, electric coercivity, is the ability of a ferroelectric material to withstand an external electric field without becoming depolarized.
