Abstract The question of how best to explain magnetic forces between uniformly moving charges has divided physicists. A fictitious dialogue styled on David Hume's Dialogues Concerning Natural Religion (1779) crystallises the various views expressed in the literature around three positions: a) special relativity can explain such forces as a relativistic aspect of electricity; b) special relativity cannot explain such forces and no explanation is required; c) special relativity cannot explain such forces and an alternative explanation is required. The arguments deployed suggest that it is possible to achieve a deeper understanding of the forces between moving charges than is commonly assumed.

关于磁力的对话

摘要如何最好地解释匀速运动的电荷之间的磁力的问题已经使物理学家产生了分歧。大卫·休ume（David Hume）的《关于自然宗教的对话》（1779）中的虚拟对话体现了文献中围绕三个立场表达的各种观点：a）狭义相对论可以解释诸如电力相对论方面的力量；b）狭义相对论不能解释这种力量，因此不需要解释；c）狭义相对论无法解释这种力量，因此需要另一种解释。所采用的论点表明，与通常假定的情况相比，有可能更深入地了解移动装药之间的力。
