| 摘 要： | 疏松载流螺线管轴线上磁场实验的设计可以测量螺线管轴线不同位置上的轴向磁场和径向磁场，实验结果与数值计算结果吻合。另外，从该实验测量结果发现疏松型螺线管轴线上的轴向磁场与螺距呈近似线性关系。这些工作不仅可作为大学物理实验课的选做内容，还可以为设计基于测量磁场的位移和应力传感器提供依据。

| Abstract: | An experiment on the measurement of the magnetic field distribution of sparse solenoid with current along its axis is designed.There is an agreement between experimental and numerical result.In addition,the experimental result shows that the axis component of the magnetic field on the axis of sparse solenoid is approximately linearly increased by the sparse solenoid pitch.This work not only as selected contents of physics experiments,but also provided the basis for the design based on the measurement of the displacement of magnetic fields and stress sensors. |
