Abstract

A new relative magnetic permeability is defined for permanent magnets, which advantageously allows to approach the non-linearity of demagnetization curve of permanent magnets. Also, using the defined quantity, we have demonstrated another form of the theorem of refraction for the surface of separation between two isotropic materials with permanent magnetization. A practical example where the defined quantities are used is presented.
