Definition: | under sinusoidal conditions in a medium where the phasors and B representing respectively the magnetic flux density and the magnetic field strength are linearly related, complex quantity Hμ_{r} defined by the relation
μ_{0}μ_{r} H
where NOTE 1 – The complex relative permeability is generally frequency dependent. For an isotropic medium the complex relative permeability is a scalar; for an anisotropic medium it is a tensor. NOTE 2 – Generally | ||

* B* =

where *μ*_{0} is the magnetic constant
__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 which represents the magnetic losses.
