| Abstract: | The coils of magnetic field in the optical magnetic resonance experiment were introduced,and the shortcomings of the traditional methods in offsetting the vertical component of the geomagnetic field were analyzed.Based on the influence of the vertical magnetic field on the magnetic resonance signal,a method of offsetting the vertical component of the geomagnetic field with good reproducibility was proposed to reduce the error caused by traditional experimental methods.This method could also be used to measure the vertical component of the geomagnetic field accurately. |
