Claim 6:
7. The torque measurement method as claimed in claim 6, wherein recheck the magnetically induced torque calculated in the sixth step, comprises:
building a physical interface on a center of an upper end of the loading tray, wherein the physical interface is configured to connect a torque screwdriver in a non-magnetic resonance imaging environment;
connecting the torque screwdriver to the physical interface, rotating the torque screwdriver to reproduce deflection angles of the loading tray of the measurement device arranged at the magnet center and loaded with the to-be-measured sample;
recording torque readings of the torque screwdriver at the respective deflection angles; and
comparing recorded torque readings of the torque screwdriver with the all calculated values of the magnetically induced torque to obtain the relative errors.
