| Abstract(in English) | In the earth's magnetic field, a magnetic structure gets a magnetization and creates a local magnetic perturbation. In order to make the magnetic structure magnetically "silent", degaussing coils are prepared in it, and currents in it those coils are controlled. For the optimal design of the coils and optimal control of the currents, the precise distribution of flux under the earth's magnetic field should be analyzed. But, the reports of such detailed analysis and measurement are few. In this paper, the disturbance of magnetic field due to a magnetic structure is analyzed, and the experimental investigation is carried out. The method of analyzing magnetic field impressed in an arbitrary direction is investigated. A suitable B-H property for such an analysis under earth's magnetic field is also examined. |
