论单极感应现象

On unipolar induction phenomenon

简单地回顾了单极感应现象的历史现状,详细地分析了被认为是判定性的Bartlett等人的单极感应实验,发现该实验使用铁管进行磁屏蔽是不合理的,指出其实验结论是值得怀疑的,并给出可能的改进方法.因此,单极感应现象理论解释问题仍然没有解决.

The history of the phenomenon of unipolar induction is reviewed, and the unipolar induction experiment of Bartlett et al is analyzed which is considered to be conclusive. It is found that using iron pipe for magnetic screen in Bartlett＇s experiment is unreasonable, and therefore their experimental conclusion is questionable. A possible method to improve the experiment of Bartlett et al is proposed. So the controversy of theoretical explanations of unipolar induction is still an open question.
