磁感应强度矢量的三维测量

大学物理实验所使用的高斯计通常只能测出空间某一点磁场的一个分量，且不能对测量点进行空间定位，为完善实验功能，改进实验效果，设计了基于霍尔效应原理的磁感应强度矢量测量仪，通过调节三维坐标架实现组合式霍尔传感器探头的移动，完成3个分量方向磁感应强度信号的测量。组合式传感器与三维坐标架的一体化结构实现了空间任意一点磁感应强度矢量的测量。

Magnetic induction intensity vector of 3D measurement

In measurement of magnetic filed, the Gauss Meter used in physical experiment of university, fails in spatial positioning on certain point, and it just could be used for measuring one component in the field. The thesis thus focuses on measuring instrument for magnetic induction vector designed on the basis of Hall Effect, so as to perfect the function and improve the effect of its experiment. The measuring instrument is being ap-plied to acquiring signals of components from three directions of the magnetic induction intensity, which is achieved through the 3D array of the Hall Sensor probe by adjusting the 3D frame. The instrument makes it possible for positioning of magnetic induction intensity vector at any point within the combined sensor employ-ing the 3D coordinate frame.
