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 .
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...
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 ...
According to the IEA's fourth quarter issue of IEA Energy, 61% of the world's natural gas vehicles (NGVs) are located in only four countries. India and China make up 16% of the NGVs in the world ...
The Euler relation for a paramagnetic system is then: = + + and the Gibbs-Duhem relation for such a system is: S d T − V d P + I d B e + N d μ = 0 {\displaystyle SdT-VdP+IdB_{e}+Nd\mu =0} An experimental problem that distinguishes magnetic systems from other thermodynamical systems is that the magnetic moment can't be constrained.
