Abstract

Abstract

The principle and factors of the Giant Magnetic-Impedance (GMI) in amorphous wire are analysed in detail. The operating principle of the sensor based on GMI is analyzed, and the signal processing circuit of micro-magnetic sensor is designed. With the characteristics of micromation and low power consumption, magnetic sensor could be used in the space magnetic-measurement.
