摘要
在利用HL-5霍尔效应测试仪测量磁场的实验中,发现有些仪器的测量曲线在磁极边缘附近存在畸变.通过磁极表面与磁极之间磁场分布的测量和磁极间磁场的分布规律的计算,分析了曲线产生畸变的原因.
Magnetic field curve distortion is found at the position of magnetic pole edge in Hall effect experiment,using HL-5 Hall effect testing instrument.The reason of the curve distortion is analyzed by measurement and calculation of the magnetic field distribution between two magnetic poles.
