Abstract

PURPOSE:To achieve a measuring experiment without being disturbed by generating the magnetic field continuously from the fine to high level eliminating earth magnetism and residual magnetism with a magnetic pole gap of an electromagnet. CONSTITUTION:Earth magnetism shall be eliminated at a measuring experiment in a fine magnetic field. An electromagnet is used to attract earth magnetism by a magnetic circuit therof. Therefore, the magnetic field in the magnetic pole gap can be eliminted close to zero by removing that including residual magnetism of a magnetic flux in the magnetic circuit. Overcoming dificulty in measuring magnetic characteristics which is to be measured continuously from the fine to high magnetic field, this enables the measuring experiment very economically.
