Using a new permeability - defined for anisotropic permanent magnets - we will demonstrate the refraction theorems of the three–dimensional (3D) magnetic field lines at the separation surface of two anisotropic materials with permanent magnetization (two permanent magnets), which have random magnetization main directions. Also, the general forms of demonstrated theorems are particularized for diverse concrete cases and an example is given to illustrate the new defined quantities.
