摘要
讨论了在交变磁场作用下的法拉第效应，并利用光电转换器、集成运算放大器和峰值保持等电路设计了一套测量液体浓度的实验装置，给出了氯化钠水溶液的费尔德系数（α）与浓度（ｃ）之间的曲线和表达式α＝α水＋０．
Basing on Faraday effect in the alternate magnetic field,a experimental device was designed for determining concentration of liquid,which consists of photo electric changer,integrated operational amplifier and peak holding circuit. With this device the relation between Field's coefficient ( α ) and concentration ( c )of Nacl water solution was obtained as follows α=α water +0.002 c
