A computerized system was designed and constructed to scan and measure localized power loss over an area of an electrical steel lamination. The local components of flux density (B) and field (H) were detected by a remote search coil and a magnetoresistive sensor respectively. The results obtained show that the power loss varies over the sample surface and the surface of individual grains. A high average loss was observed over a grain with a yaw angle of 7[degree], the minimum average loss was measured in a grain with a tilt angle of approximately 2[degree] to 3[degree]. The bulk average power loss over an area is comparable to that of a Single Strip Tester (SST).
