Measurement of Barkhausen noise and its correlation with magnetic permeability
چکیده انگلیسی

The paper investigates applicability of the Barkhausen noise technique as a non-destructive testing method and its correlation with the magnetic hysteresis measurement. The hysteresis and the Barkhausen noise experiments were performed at laboratory and industrial configurations on a model series of open flat samples plastically deformed by mechanical tension. The sample magnetic field was measured with the help of a near-surface Hall sensor. The results proved interrelation between the magnetic differential permeability and the Barkhausen noise envelope. However, significant quantitative discrepancies between them were also obtained. The reasons of these deviations as well as the main measurement problems were discussed in order to help to standardize the Barkhausen noise technique and to extend a number of the used parameters for the non-destructive testing.
