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 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: where See more Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive See more In the macroscopic formulation of electromagnetism, there appears two different kinds of magnetic field: • 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 … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic … See more The following table should be used with caution as the permeability of ferromagnetic materials varies greatly with field strength.
