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 … 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 … See more For gyromagnetic media (see Faraday rotation) the magnetic permeability response to an alternating electromagnetic … See more • Antiferromagnetism • Diamagnetism • Electromagnet • Ferromagnetism See more Relative permeability, denoted by the symbol $${\displaystyle \mu _{\mathrm {r} }}$$, is the ratio of the permeability of a specific medium to … 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, … 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 permeability (at or near 0 T) of 2,000 and a maximum of 35,000 and, indeed, the relative … See more WebPermeability — TRAN-COR H-1 Oriented — TRAN-COR H-0 DR — TRAN-COR H-1 DR Grade Designations The American Iron and Steel Institute type numbers and AK Steel designations for electrical steel grades con-sist of the letter M followed by a number. The M stands for magnetic material; the number is representative of the core loss of that grade.
