Abstract

Abstract : Coercive force of grain-oriented electrical steel applied in cigarette machines is tested by a novel NDT method in which Barkhausen noise was applied. Linear relationship between coercive force and Barkhausen noise of conventional and high-permeability electrical steel was built and the precision of the model was verified. Experimental results show that the coercive force is linearly related to Barkhausen noise. The variation of coercive force with magnetic induction intensity increase was also interpreted in view of magnetic domain changing process, and the correlation formula derivation of MBN and coercive force domain wall was illustrated as well.
