This paper presents the distributions of local magnetic properties in a grain-oriented silicon steel sheet (23ZH) without insulator coating, measured by using the two-dimensional magnetic sensor. It is well known that the local distributions of the flux density B and the field strength H in a grain-oriented silicon steel sheet are not uniform due to orientation. The properties, namely, the H-vector, the B-vector, the hysteresis loop and the iron losses are depending on the local orientation in a grain. The result shows the relationship between the magnetic properties and the grain structure in the specimen.
