WebThe permeability of ferromagnetic materials is not constant, but depends on H. In saturable materials the relative permeability increases with H to a maximum, then as it approaches saturation inverts and decreases toward one. [2] [3] Different materials have different saturation levels. 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 William Thomson, 1st Baron Kelvin in 1872, and used alongside permittivity by Oliver Heaviside … 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, … 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, an external magnetic field alters the orbital velocity of electrons around their atom's … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic … See more • Antiferromagnetism • Diamagnetism • Electromagnet 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 The following table should be used with caution as the permeability of ferromagnetic materials varies greatly with field strength. For example, 4% Si steel has an initial relative … See more
