| The Barkhausen noise was measured in plastically deformed low-carbon steel at various frequencies of the magnetizing field. Strip samples magnetized by a yoke were used for investigation. The measured amplitude distributions and power spectra are compared with the results of the Alessandro, Beatrice, Bertotti, Montorsi model of the Barkhausen noise. The measurement results at the triangular magnetizing current and the triangular magnetic field in the sample were compared and the differences will be discussed. |
