库仑早在1785年就用有名的扭称实验,证明了两磁极间的相互作用力反比于距离平方,并从而得出了磁的库仑定律。但依磁的分子电流学说,我们知道磁极并不真正存在,而磁极间的相互作用,实际上只是分子电流相互作用的一种特殊表现。在这篇短文中,我们将根据电流相互作用的有关公式,应用简单的数学,推导出磁的库仑定律。
As early as 1785, Coulomb used the famous twisting experiment to prove that the interaction between the two poles was inversely proportional to the square of distance, and thus the magnetic Coulomb’s law was obtained. However, according to the molecular current theory of magnetism, we know that the poles do not really exist, and the interaction between the poles is actually only a special manifestation of the molecular current interaction. In this essay, we derive the Coulomb’s law of magnetism by applying simple mathematics based on the relevant equations of current interaction.
