The results of fractal analysis of images of the surface of a permanent magnet NdFeB (N35 brand) obtained by the polar Kerr effect method using an indicator bismuth-containing ferrite-garnet film after magnetization reversal by a pulsed field of 0.1-2 T are presented. Two different methods of changing the magnetic field are used: sequential change in the magnitude of the magnetic pulse and magnetization to saturation before each acting pulse. A correlation between the form of the field dependences of the fractal dimension of the profile of magneto-optical images of the magnet surface DL(H) and the corresponding dependences Mr(H) is established. The obtained data are compared with the results of a similar fractal analysis of the KC37 (SmCo) magnet. Keywords: fractal dimension, remanence, field dependences, Kerr effect, ferrite-garnet film.
