where *μ*_{0} 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 __μ___{r} is expressed as __μ___{r} = *μ*'_{r} − j*μ*''_{r} where *μ*'_{r} is the real relative permeability and *μ*''_{r} is the magnetic loss index that represents the magnetic losses.
