The permeability of vacuum (also known as permeability of free space) is a physical constant, denoted μ 0. The SI units of μ are volt-seconds/ampere-meter, equivalently henry /meter. Typically μ would be a scalar, but for an anisotropic material, μ could be a second rank tensor . 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, … See more The following table should be used with caution as the permeability of ferromagnetic materials varies greatly with field strength.

WebPermeability is a magnetic property of a material, and is often expressed as μ 0 x μ R, where μ 0 is a physical constant equal to exactly 4*pi*10 -7 Henries/meter and μ R is the relative permeability. μ R is equal to one for free space, and a whole lot of other materials including gold and copper. WebFor non-ferrous metals such as copper, brass, aluminum etc., the permeability is the same as that of "free space", i.e. the relative permeability is one. For ferrous metals however the value of µ r may be several hundred. Certain ferromagnetic materials, especially powdered or laminated iron, steel, or nickel alloys, have µ r that can range ...
