DEVICE AND METHOD FOR MEASURING AMBIPOLAR MAGNETIC TORQUE OF SPACE MAGNET AND METHOD FOR COMPENSATING AMBIPOLAR MAGNETIC TORQUE OF SPACE MAGNET

摘要

A device and method for measuring ambipolar magnetic torque of a space magnet and a method for compensating ambipolar magnetic torque of a space magnet are provided. The device comprises a space magnet (1), a support bar (2), a rotatable rack (3), a steeve (4), Helmholtz coils (5), a bearing seat (6), a dynamometer (7) and a fixation mount (8). Rotary torque is generated by the interaction between the magnetic field generated by the Helmholtz coils (5) and the torque of the space magnet (1). The Helmholtz coils (5) subject to the action of the rotary torque, and are rotated by rotatable rack (3) and the steeve (4) on the support bar (2) loaded on the bearing seat (6). The ambipolar magnetic torque of the magnet is measured by measuring the rotary torque of the Helmholtz coils (5).
