    • PROBLEM TO BE SOLVED: To provide a magnetic field applying device capable of uniformly generating an intense magnetic field in a wide range with reduced power.
      SOLUTION: In the magnetic field applying device, recessed parts of two cores whose cross sectional surfaces have U-shapes are freely movably constituted in a position bonded to each other and a position separated from each other in a direction opposed to each other. In the position bonded to each other, tip parts of one sides of U-shaped two sides nearly parallel to each other come in contact with each other and the other sides do not come in contact with but come close to each other. Thereby, the intense magnetic field can be generated with reduced power. Intense magnetic field can be uniformly applied to a wide range of a long bar-shaped magnetic field applied object by providing the magnetic field applied object on the tip part of one side of the sides coming close to each other. Thereby, measurement of many elements at a time is enabled when resistance is measured by application of a magnetic field.
