Abstract
This paper presents a new method for testing electrical steel sheet, b ased on measurements of the magnetic field distribution over the sheet surface. The tangential field value is measured with the aid of a per malloy magnetoresistive sensor. The field distribution is displayed in the form of a colour map, hence the method is called 'magnetovision'. The repeatability of the maps is excellent. The most interesting new results of electrical steel investigations are presented. The system p rovides a versatile tool for non-destructive quality control and for t he determination of the structural uniformity of electrical steel. Mag netovision, compared with other methods, seems to be especially useful for detecting the causes of steel quality deterioration.
