Zusammenfassung:A possibility of interpolating the nonlinearity factor of the ferromagnetic media over a wide range of magnetic fields using a system of functions has been demonstrated. As a result of the serendipitous choice of functions, fairly simple formulas for calculating magnetic field generated by a flaw both inside and outside the ferromagnetic medium have been obtained.
