自制霍尔效应演示仪

Self-made Hall effect demonstration device

利用霍尔效应原理制作了霍尔效应演示仪,详细介绍了该演示仪的制作过程,定性地演示了霍尔电压与通电电流和磁感应强度的关系.

This paper detailed the making process of a self-made Hall effect demonstration device,and illustrated qualitatively the relationship between Hall voltage,electric current and magnetic induction.
