摘要
基于电磁感应原理,自制"双电机"传感器,通过多个电路模块进行数据收集及处理,可以测量小于1mT的弱磁场。介绍了测量系统的组成及各部分的具体设计。
Based on the fundamental principle of the electromagnetic induction,the sensor of double-motor was made by us.This method reaches the goal of measuring the weak magnetic field,of which the magnitude is less than 1mT,by collecting,processing and analyzing the data obtained from multiple electric circuit modules.
