Effect of Sensor Configuration on Magnetic Barkhausen Observations

Abstract

Abstract A number of characteristics of the magnetic Barkhausen signal, including power density, autocorrelation, jumpsum density, and noise emission rates, are obtained with different sensor types on low-carbon sheet steels and compared. The steel samples used in this study produced single, narrow Barkhausen peaks and the shapes of the rms voltage and jumpsum curves were found to be nearly independent of the sensor type.
