Abstract
The Barkhausen noise was measured in plastically deformed low-carbon steel at various measurement conditions. Strip samples magnetized by a single yoke were used for investigation. The measurement results for different magnetizing frequencies, waveforms of the magnetizing field and cut-off frequencies of the processing filter were compared and the differences, mainly concerning the sensitivity of the Barkhausen noise on the plastic deformation, will be discussed.
