电磁学与电动力学中的磁单极—V

MAGNETIC MONOPOLE IN ELECTROMAGNETISM AND ELECTRODYNAMICS—V

作为本系列5篇文章的最后一篇,作者在电磁学和电动力学框架内用尽量科普的方式对比前4篇文章介绍一个磁单极很不奇特的性质.本文主要研究用小电流圈定义的磁偶极子和用正负磁单极对定义的磁偶极子的差别.文章仔细讨论一个在2012年曾在业界引起很多争议的由一个点电荷和一个磁偶极子构成的体系的可能的现象,并展示对这个体系,由正负磁单极对构成的磁偶极子比由电流圈构成的磁偶极子要简单和平庸许多.

As the last one of a series of five individual papers and in contrast to previous pa- pers, we introduce a special non-peculiar property of magnetic monopole as popular science in the frameworks of electromagnetism and electrodynamics. In this paper, we mainly focus on the differences of magnetic dipoles defined by small current loop and that by the positive and negative monopole pair. We will analysis the possible phenomena for the system consisted from a point charge and a magnetic dipole, and show that the magnetic dipole constructed by the positive and negative monopole pair is much simple and trivial than that by current loop.
