利用霍尔元件开发的新实验

New Experiments Developed Using Hall Elements

基于霍尔元件电阻率随温度线性变化的特点,设计一套大学物理实验教学项目。该项目可以使学生研究其电阻率与温度的关系,制作霍尔元件材料的微观参数与温度的关系。实验拓宽了霍尔元件的应用范围,激发学生的联想思维。

A university physics experimental teaching project is proposed based on temperature dependence resistivity characteristics of Hall devices.In this project,students could study the relation between the resistivity and the temperature,and find the internal relation between microscopic parameters and the temperature.This project not only extends applications of Hall devices,but inspires students’associative thinking.
