The systematic effects of applied current amplitude to the magnetising coil, distance between the poles of the EM yoke, magnetic excitation frequency, sensitivity and frequency response of MBN pick-up coil and the geometry of the test sample on the applied magnetic field strength, tangential magnetic field strength and the Magnetic Barkhausen Noise (MBN) signal profile are presented in this study. The influence of different parameters is discussed with measurement results obtained from a harder case-carburised steel and a softer spheroidised annealed steel samples. This study shows the importance of maximising the shape of the MBN profile for appropriate evaluation of ferritic steels.
