Explaining Unipolar Induction via Bipolar Induction Experiments with a Spherical Magnet
摘要: 分析指出单极感应磁体磁力线相对于转轴的全对称分布状态没有被引起足够的重视，是导致单极感应问题产生和遗留的根本原因。提出了一种两极球形磁体验证单极感应问题的方案。方案实施容易。只要选择合适的转轴取向，同一磁体既可以实施经典的单极感应，又可以实施找寻单极感应问题答案的两极感应验证实验。两种实验步骤对应实施，实验结果可对比分析。与单极感应全部实验结果两种观点都可以给出合理的解释不同，两极感应验证实验时磁体的磁力线相对于转轴的分布已不再是全对称状态，因此对于验证结果两种观点能给出的合理解释差异凸显出来，对与错已显现。验证结论是：磁体的磁力线随磁体运动。
Abstract: This paper highlights the overlooked factor contributing to the unipolar induction paradox, which is the lack of attention to the fully symmetrical distribution of magnetic field relative to rotation axis in the experimental setup. To address this, the paper proposes a set of bipolar induction experiments using a spherical magnet to explain unipolar induction. The proposed experiment is easy to implement --- we can perform both the classic unipolar induction and the bipolar induction experiments by selecting different orientation of the rotation axis with the same magnet. The two sets of experiments can be conducted following their respective procedures, and the results can be conveniently compared and analysed. In contrast to the unipolar case where both viewpoints provide reasonable explanations for all results, the difference between the explanations given by the two viewpoints becomes apparent in the bipolar induction settings. This is due to the distribution of magnetic field lines in the magnet relative to the rotational axis no longer being fully symmetrical. Such differences between the two viewpoints in the asymmetric settings allow us to verify their correctness. Our analysis shows that magnetic field lines move with the magnet.
