Abstract
Barkhausen noise (BN) measurements were made on a half section of a pipe as a function of sweep rate. Power spectral analysis and pulse height distribution studies weremade on the BN data. The rms BN voltage was found to increase with increasing sweep rate. The power density of BN spectra was found to increase and BN jumps with large amplitude take place at higher sweep rates. Increasing sweep rate is also found to increase the total number of BN jumps.
