This contribution deals with an observation of the magnetic dynamic of different types of the machined surface of bearing steel. The Bakhausen noise (BN) measurements are presented here as commonly introduced in industry for quality control due to the extremely sensitivity of the magnetic domains wall dynamics to the microstructure of material. The results of magneto-optical measurements are presented with the goal to explain the observed BN anisotropy. It is shown that BN anisotropy is associated with uniaxal magnetic anisotropy introduced by hard milling which causes the principally different magnetic reversals processes in orthogonal directions.
