Chaotic behavior of Barkhausen noise induced in silicon steel sheets

This paper presents chaotic behavior of the Barkhausen noise generated in magnetic fields. This noise is generated by the magnetization jumps caused by abrupt depinning of magnetic domains. We have studied the application of the noise to nondestructive testing techniques. The results showed that the Barkhausen noise could be continuously generated in a rotational magnetic field and it was within the bounds of possibility that the signal had information referent to defects or flows in measuring materials. In this paper, we investigated to make the existence of chaos in the Barkhausen noise clear from the reconstructed attractor by embedding
