IEVref: 121-12-30 ID: Language: en Status: Standard Term: complex relative permeability Synonym1: Synonym2: Synonym3: Symbol: μr Definition: under sinusoidal conditions in a medium where the phasors B and H representing respectively the magnetic flux density and the magnetic field strength are linearly related, complex quantity μr defined by the relation B = μ0μr H where μ0 is the magnetic constant Note 1 to entry: The complex relative permeability is generally frequency dependent. For an isotropic medium, the complex relative permeability is a scalar quantity; for an anisotropic medium, it is a tensor quantity. Note 2 to entry: Generally μr is expressed as μr = μ'r − jμ''r where μ'r is the real relative permeability and μ''r is the magnetic loss index that represents the magnetic losses.
