For the first time it has been proposed to use magnetic field lines as a tool for the quantitative description of surface defects in soft magnetic ferromagnets. By measured at a certain distance from the surface of a ferromagnet, the values of the scattering magnetic field, created by defects, it is possible to restore the field values in a ferromagnet and then build the magnetic field lines. The magnetic field lines in soft magnetic ferromagnets with great accuracy coincide with the boundary of a ferromagnet - air.
