Recently, the efficiency of electromagnetic machinery and apparatus has progressed day by day, as a result of significant advances in the production of electromagnetic steel. However, a large decrease of the iron loss is necessary for further improvement of the efficiency. To achieve this, it is necessary to determine the magnetic properties of every crystal grain and its behavior at grain boundary, because the size of a crystal grain in grain-oriented silicon steel is relatively large. Though determination of the two-dimensional magnetic properties has been recognized as a useful method in magnetic analysis, ordinary two-dimensional magnetic measurement is not suitable for local measurement, owing to the properties of the measurement method. We therefore carried out local measurement by the needle probe method, and make it clear the magnetic properties of the crystal grains and grain boundary.
