Torque was detected in a steel shaft with a ring-sharped surface by using a magneto-impedance effect sensors whose heads were placed on the two edges of a gutter in the ring-shaped surface. The hysteresis removal was done utilizing two different shapes of the hysteresis of torque detection at the two egges. A large pulse current was a priori applied through the shaft to induce circumferential magnetic anisotropy in order to remove the magnetic poles at the gutter edge for zero torque.
