摘要
对霍耳效应测量磁感应强度的实验原理作了分析,讨论了外界定向干扰磁场对实验的影响、指出在实验教学中,相邻霍耳效应测量仪摆放距离宜大于等于2.5m才能忽略相互干扰.
The theories of measuring magnetic induction in Hall effect experiment are analysed and external magnetic field that influence the experiment are studied. Furthermore it has been proved that the influence may be ignored if the distance of the instruments is longer than 2. 5 m.
