应用霍尔效应实现了对角度改变的显示,把一个非电学量转换成电学量输出,容易实现对角度的测量和自动控制.指导学生利用霍尔元件制作了角位移传感器演示装置,不仅拓展了“霍尔效应测磁场”这一大学物理实验的内容,而且加强了物理实验在工程技术应用的实现和训练.
Using the Hall effect to achieve the display of the angle change, convert a non-electrical quantity into an electrical quantity output, easily realize the angle measurement and automatic control. Instruct the student to use the Hall element to make the angular displacement sensor demonstration device, which not only expands “Hall effect magnetic field” is the content of this university physics experiment, and it also strengthens the implementation and training of physics experiments in the application of engineering technology.
