《电磁学下》是《电磁学》的第二学习进程，教学内容含恒磁场、磁介质，电磁感应、交流电和电磁场电磁波。虽然《电磁学下》内容比较多，但是处理场的基本方法大家已经熟悉和适应了，应该说，电磁学的前两章是整个电磁学的基础。建议大家学习了第一进程，通过了结业考试以后再进入第二学习进程《电磁学下》的学习。本课程的课程是按照知识点设置模块，《电磁学下》包含6个模块。每个模块又包含几节课，每个模块结束有一个小测，同学们可以自我测试，没有时间限制，大家可以根据自己的需要和时间安排来自主学习，以免一步跟不上，步步跟不上，这对于学习我们这种理论性比较强的课是有利的，已经明白的可以跳过去，不清楚的可以重点学习。
教学大纲

模块一 : 恒定磁场的基本规律
本模块一总共有三节课，第一课向大家介绍前辈大师建立磁场的一些研究成果，目的在于让同学们了解物理学发展历史上一些极其重要的创造性的工作，期望通过对这些案例的介绍，让大家体会物理学是如何发展起来的，科学家是如何工作的，也可以让同学们欣赏这些卓越的工作；第二课主要介绍磁感应强度的定义，利用毕奥-萨筏尔定律和叠加原理求电流产生的磁感应强度；第三课是讲解了磁高斯定理和安培环路定理。这些应该是学习磁场基本规律最核心的内容，要求掌握如何运用微元法求磁感应强度，也要求会利用安培环路定理求电流具有对称性分布所产生的磁感应强度。应该看到，通过学习电场的规律，我们的已经了解处理场的方法，学会了利用对称性和微元法来解决问题，虽然磁场的规律与电场不同，但作为处理场的问题，都是具有连续分布客体的特点，因而，可以借鉴求电场强度的经验来处理已知电流分布求磁感应压强度的问题，只是要注意磁场与电场的区别，即电场力是径向力，而磁场力是横向力，因而两种场的性质是不同。前者是有源无旋场，后者是无源有旋场。在求磁感应强度的问题中，还要注意掌握叉乘的规律，注意空间方向性等。与微元法求磁感应强度的问题相应于《大学物理通用教程》电磁学p177 4-2、6、7、8、9，与利用对称性和安排环路定理求磁感应强度的问题相应于《大学物理通用教程》p178 4-11、12、14。习题比较多，大家要耐着性子坚持下去，坚持就是胜利！
本模块也有一些练习题，主要注重对概念的理解，同学们可以作为自我测试，独立完成。
