Magnetic Amorphous Micro-Force Sensor

In this paper the innovative method of microforce measurement based on air gap influence on magnetic circuits properties is presented. Magnetic ribbon core with air gap is put under transverse compressive stress perpendicular to the magnetic field direction generated by low-mass calibration weight. Change of the air gap induced by the force acting on the core causes change of its magnetic parameters. The possibility of utilization of various magnetic amorphous materials is investigated. Obtained results indicate a possibility of application of the developed sensor in microforce measurements.
