Магнитная дефектометрия поверхностных дефектов в ферромагнетике

Abstract

For the first time it has been proposed to use magnetic field lines as a tool for the quanti-tative description of surface defects in soft magnetic ferromagnets. By measured 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 mag-netic ferromagnets with great accuracy coincide with the boundary of a ferromagnet - air.
