| Abstract: | Measuring of the geomagentic inclination is difficult and its exactness is low,because the earth-magnetic field is so weak and about 10-5 T.This article has a discussion about the application of a new anisotropic magnetoresistive sensors for measuring the geomagentic inclination and the experiment finds that the new magnetoresistive sensors have the advantages of simple operation,high sensitivity and exactness when applied in the measuring of geomagentic inclination.Except its application value,the experiment is also suitable for the college physical experiment. |
