摘　　要：根据毕奥—萨伐尔定律,得出了螺线管轴线上的磁场分布解析表达式,由霍尔效应实验原理,对其实例进行测量,利用Mathematic软件,对螺线管轴线上的磁场分布进行数值运算,把理论结果与实验结果进行比对,发现吻合度很好。According to the law of Beaufort,the analytical expression of the magnetic field distribution on the axis of the solenoid is obtained,and an example is measured based on the experimental principle of Hall effect,the theoretical results were compared with the experimental results,and a good agreement was found.
