What is Barkhausen Noise Analysis?

Barkhausen noise analysis is a non-destructive method involving the measurement of a noise like signal induced in a ferromagnetic material by an applied magnetic field. There are two main material characteristics that will directly affect the intensity of the Barkhausen noise signal: hardness and stress. The noise intensity continuously decreases in microstructures characterized by increasing hardness, and compressive stresses will decrease the intensity of Barkhausen noise while tensile stresses increase the intensity.

 

Measurement Process

Performing Barkhausen noise measurements is a simple process:

  1. Measurement area is magnetized with alternating magnetic field by the sensor
  2. During magnetization the sensor measures the Barkhausen noise signal and transfers it to Rollscan
  3. Real-time measured values are displayed on Rollscan and/or the ViewScan software
