霍尔效应测量磁场实验的拓展

Development of the Experiment of Measuring Magnetic Field with Hall Effect

利用霍尔效应测二维空间磁场分布的拓展方案,测量了马蹄形磁铁周围的磁场分布。并用Mathematica编程对测量数据进行处理,模拟了直观形象的磁场分布图,提高了实验结果的精确度。

The magnetic field around the horseshoe magnet was tested,using development scheme that measure two-dimensional magnetic field by Hall effect. The data was processed and the distribution of magnetic field was simulated by Mathematica program,the simulated image of magnetic field distribution was more intuitive. Also improves the accuracy of the experimental results.
