英文摘要：

The function of magneto resistance sensor effect is briefly introduced. Relationships between GMR and magnetic field as well as output coming from AA002 series analog sensors and magnetic field are measured by using the AA002 series analog sensors. Based on the experimental results, its characteristics are analyzed. A series of physics experiments using giant magneto resistance sensor is designed.
