摘要
设计了用霍尔效应法测量磁场的实验方法。测量电路以霍尔元件5303为核心器件,通过改变霍尔元件的输入参数及测量位置,验证了霍尔效应理论及所测磁场的特性。实验表明,该方法可有效测量通电长直螺线管中的磁场分布,从实验角度验证霍尔效应理论。
This paper designed a magnetic field measurement method using Hall-effect, which selected the Hall element 5303 as the key electronic component; and verified the Hall-effect theory and the characteristic of the measured magnetic field by changing the input parameters of the Hall element and the measure point. The experiment proved that this method can measure the magnetic field distribution of the power solenoid effectively and verify the Hall-effect theory from the experimental point.
