Research of the Magnetic Field in Optical Pump Magnetic Resonance Experiment

Abstract

In the experiment of optical pumping magnetic resonance, the calculation of horizontal and vertical magnetic fields is related to the accuracy of the final results, therefore, the construction of correct calculation method of horizontal and vertical magnetic field is very important for the experiment. First, the article analyses the relation between magnetic field of the Helmholtz coil and current. Then, based on the widely used optical pumping magnetic resonance experiment instrument, the article analyzes the differences of the winding method of coil for horizontal and vertical magnetic field (parallel and series), and gets correct calculation methods and the corresponding formulas of the horizontal and vertical magnetic field for different cases. Finally, the results are proved by the experiment of optical pumping magnetic resonance. The research can not only improve the accuracy of the optical pumping magnetic resonance experiment, but also enhance the scientific research and innovation ability of the students.
