Possible application of amorphous wire as a sensor of angle of rotation, direction of rotation and torque

Stress changes the domain structure in magnetostrictive materials and consequently changes the magnetization. From this, one can imagine possible sensor applications based on the stress-magnetic effect of the wires. In this work, the authors have studied the stress-magnetic characteristics of amorphous wires and subsequently proposed possible applications for the wires based on the stress-magnetic effect. The proposed possible applications are, for instance, sensing of angle of rotation, direction of rotation and sensing of magnitude of torque.
