Abstract

The influence of sample thickness and grain size of Conventional Grain-Oriented (CGO) and High Permeability Grain-oriented (HGO) steels on Magnetic Barkhausen Noise (MBN) of Epstein strips has been examined. It might be expected that MBN decreases with increasing sample thickness due to eddy current damping but the measurements show that the average domain width, hence the grain size influences MBN in strips less than 0.35 mm thick. From 0.35 mm and above, both strip thickness and domain width influence MBN in CGO and HGO.
