摘要
根据霍尔效应原理测量磁场的分布和低压直流电位差计的使用是大学物理实验中的基础实验项目.把霍尔效应实验仪与低压直流电位差计相结合,不但可以提高磁场测量的精确度,并且能够引导学生开拓思维,给学生提供开展创新实验的一个新思路,从而多方面培养学生的创新能力.
The Hall effect principle of measuring the DC potentiometer, are universitybased pilot project magnetic field distribution and the use of low voltage in physics experiments. The Hall effect experiment instrument and the combination of low voltage DC potentiometer, not only can improve the accuracy of magnetic field measurement, and also can guide students to develop thinking , innovative experiments carried out to provide students with a new idea, and many students ability to innovate.
