经典电磁学(英语:Classical electromagnetism)或经典电动力学是理论物理学的分支,通常包含在广义的电磁学,以麦克斯韦方程组和洛伦兹力为基础,主要研究电荷和电流的电磁场及其彼此的电磁相互作用。当相关尺度和场强足够大以至于量子效应可忽略时(参见量子电动力学),这一套理论能够对电磁现象提供一个非常漂亮的描述。有关经典电磁理论的综述以及物理概念的详细解说可参见费曼、莱顿和桑斯;帕诺夫斯基和菲利普;以及杰克逊 等人的专著。
论述了经典电磁学的基本方程最少应有几条。
The minimum of the basic equations of classical electromagnetism is discussed.
经典电磁学的规律的数学表述,有许多种不同的结构方案,它们各有其缺点。
For the mathematical description of the basic laws of the classical electromagnetics there existed some different systems and each of them has its own shortcomings.
通常可以表示为大量子数目情形下量子力学“减少”到经典力学和经典电磁学。
This is often expressed by saying that in case of large quantum numbers quantum mechanics "reduces" to classical mechanics and classical electromagnetism .
