| Abstract: | This article discusses the application of a new magnetoresistive sensor for measuring the earth-magnetic field. In particular, we determine the direction of geomagnetic meridian plane and measure magnetic declination by using a new method which has the advantages of simple operation and high precision. In the experiment, students can easily master the key points of operation and experimental teaching has very good results. |
