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: See more Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field.
