Abstract: Measurement of the earth-magnetic field is difficult and its exactness is low,because the earth-magnetic field is so weak and about 10-5 T.This article discusses about the application of a new anisotropic magnetoresistive sensors for measuring the earth-magnetic field.It is found form the experiment that the new magnetoresistive sensor has the advantages of simple operation,high sensitivity and exactness when the measuring of earth-magnetic field is applied.Except its application value,the experiment is also suitable for the college physical experiment.
Key words: magnetoresistive sensors, Helmholtz coil, sensitivity, earth-magnetic field, magnetic induction intensity, geomagnetic inclination, college physical experiment
