| 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。

| Abstract: | Aiming at the problem of experiment teaching,the accurate parameters standardization of Hall and magnetic field electricity (Is and IM) was studied by given hall sensitivity,then the error of magnetic field values was calculated.The results showed that the error of values was minimum whileIs was 1mA and IM was 100mA and the position of magnetic field was x=0mm and KH=169mV/mA.This finding could use to the teaching of university experiments. |
