Relative permeability sign
Relative permeability, denoted by the symbol $${\displaystyle \mu _{\mathrm {r} }}$$, is the ratio of the permeability of a specific medium to the permeability of free space μ0: $${\displaystyle \mu _{\mathrm {r} }={\frac {\mu }{\mu _{0}}},}$$ where $${\displaystyle \mu _{0}\approx }$$ 4π × 10 H/m is the magnetic … See more In electromagnetism, permeability is the measure of magnetization that a material obtains in response to an applied magnetic field. Permeability is typically represented by the (italicized) Greek letter μ. The term was coined by See more Diamagnetism is the property of an object which causes it to create a magnetic field in opposition of an externally applied magnetic field, thus causing a repulsive effect. Specifically, … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic field in the microwave frequency domain is … See more • Antiferromagnetism • Diamagnetism • Electromagnet See more In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • the magnetizing field H which is generated around electric currents and displacement currents, and also emanates from the poles of magnets. … See more Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field.
