| 摘 要： | 针对大学物理实验中＂霍尔效应法测量磁场＂项目只能测长直螺线管轴线上一维稳恒磁场分布的不足,提出一种设计方法,来测量任一未知稳恒磁场的二维分布,进而可扩展到测量三维分布。可使学生深刻全面理解霍尔效应测磁场的原理及磁场的性质,并可作为设计性实验项目在大学物理实验课中开出,培养学生的创新意识。

| Abstract: | In view of the disadvantage that one-dimensional distribution of magnetic field on midfield axis inside straight solenoid is only measured in the experiment ＇using Hall effect to measure magnetic field＇,a simple and feasible method to measure two-dimensional distribution of any magnetic field and extend to the three-dimensional one is designed.This design can not only make students understand deeply the principle of measuring magnetic field based in Hall effect and the property of magnetic field,but be used as a designed experiment of college physics experiment. |
