亥姆霍兹线圈的磁场及其测量

Magnetic Field in Helmholtz Loop and Measurement

给出了一种测量亥姆霍兹线圈磁场分布的一种新方法。利用单片机技术将霍耳探头所检测到的磁感应强度的信号显示到点阵屏上,在磁场中移动霍耳探头即可将亥姆霍兹线圈轴线上磁场分布规律以曲线和数显的形式显示出来。在教学和科研中具有一定的使用价值。

The authors provide a kind of new method by which magnetic field distribution in Helmholtz loop is measured. By utilizing single-chip computer technology, magnetic intensity signals that are detected with Hall probe are shown on a lattice screen, and with the movement of Hall probe at the axis of Helmholtz loop,the distribution of magnetic field is shown through the form of curve and digital display. The new method has certain application value in teaching and scientific research.
