S. Tumanski et M. Stabrowski, MAGNETOVISION SYSTEM - NEW METHOD OF INVESTIGATING STEEL SHEETS, Journal of magnetism and magnetic materials, 160, 1996, pp. 165-166
A method for the automatic analysis of the magnetic field distribution
s at the surface of electrical steel sheets is presented. The results
are presented in the form of a contour map on a VDU screen. A magnetor
esistive probe with eight Permalloy sensors is used. The main design a
nd development problems are described. Some details of the magnetovisi
on system for testing steel sheets are presented.
