| Abstract: | Through the experimental design of optical pumping magnetic resonance, under different combination conditions of horizontal field, sweeping field, and the geomagnetic field, the optical pumping magnetic resonance signal was observed and recorded. By using the linear fitting, we calculate the factor of rubidium atoms,and the measurement error is only 0. 24% ;then under a fixed radio frequen- cy, we measure that geomagnetic field of Chongqing region is 0. 3918 GS. The application of the experiment has an innovative,practical value in teaching content. |
