DETERMINATION OF THE SURFACE OF DEFECT LOCATION AND RESTORATION OF ITS GEOMETRIC PARAMETERS BY THE MFL METHOD WITH ONE-SIDED ACCESS TO THE FERROMAGNETIC PLATE
DOI: 10.17804/2410-9908.2021.6.045-053 The paper presents a theoretical and experimental confirmation of the technique allowing the surface of defect location and its geometric parameters to be determined from measuring the values of the magnetic field components above one of the surfaces of a magnetically soft ferromagnetic plate. The technique allows one to take into account the nonlinearity of the response of a ferromagnet to an external magnetostatic field.
