PURPOSE:To enable a highly accurate testing, by arranging a conducting test object in a uniform normal magnetic field to run current to the test-sample crossing the flux of the magnetic field. CONSTITUTION:A conducting test sample 30 is arranged in a uniform normal magnetic field 10 and both ends of a discharge circuit 20 are connected to the test sample 30 to flow current in the direction crossing that of the flux of the magnetic field 10. Consequently, a magnetic force is generated in the test sample 30 according to the direction and the intensity of current to impart a uniform load thoroughly at a high accuracy without causing vibration and repulsion in the test sample 30. The load also is calculated from values of current and the magnetic field at a high accuracy. Moreover, this eliminates any load transmitting body which applies a load to the test sample 30 in contact therewith thereby facilitating the testing under a special condition. |
