摘要
针对实验教学中存在的问题,在给定霍尔灵敏度的情况下,标定了霍尔电流(Ιs)和励磁电流(IM),并测量了不同情况下的磁场误差。研究表明:磁场稳定位置x=0 mm左右且KH=169 m V/m A时,其Is和IM选取1 m A和100 m A时,误差最小,较为准确,该结论可用于大学物理实验教学。
Aiming at the problem ol experiment teaching, the accurate parameters standardization ol Hall and magnetic field electricity （Is and IM） was studied by given hall sensitivity, then the error ol magnetic field val-ues was calculated.The results showed that the error ol values was minimum while Is was 1 mA and IM was 100 mA and the position of magnetic field was x = 0 mm and KH = 169 mV/mA.This finding could use to the teach-ing of university experiments.
