摘　　要：搭建了能够测量长直小口径螺线管轴线磁场的装置,测量了霍尔片的霍尔系数,并用改进的霍尔片测量了矩形和圆形截面螺线管轴线磁场强度大小。通过拟合实验数据并与理论值比较,表明装置的可靠性较好。本研究为测量小口径螺线管内部磁场提供了一种可行的方案。A device was built to measure the magnetic field of the axis of solenoid with long straight and small diameter.The Hall coefficient of the Hall element was measured,and the magnetic field intensity of the rectangular and circular solenoid axes was measured with the improved Hall element.By fitting the experimental data and comparing with the theoretical values,the reliability of the device is better.A alternative scheme is provided for measuring the internal magnetic field of the solenoid with small diameter.
