中文简介: | 从自然界最基本的过程到尖端的电子设备,电和磁主宰着我们周围的大部分世界。电场和磁场是由带电粒子产生的。带电粒子也能感受到电场和磁场中的力。麦克斯韦方程组除了描述这种行为外,还描述了电磁辐射。 在本课程中,我们将完成电学和磁学的介绍。我们首先考虑磁场随时间变化,通过法拉第定律和电路中的电感器工作。通过增加位移电流,我们完成了麦克斯韦方程组。我们通过探索自由空间中麦克斯韦方程组的解——电磁辐射来完成本课程。 |
课程简介: | Electricity and Magnetism dominate much of the world around us – from the most fundamental processes in nature to cutting edge electronic devices. Electric and Magnet fields arise from charged particles. Charged particles also feel forces in electric and magnetic fields. Maxwell’s equations, in addition to describing this behavior, also describe electromagnetic radiation. In this course, we finish up this introduction to Electricity and Magnetism. We begin by thinking about magnetic fields that change in time, working through Faraday’s Law and Inductors in Circuits. With the addition of Displacement Current, we complete Maxwell’s Equations. We finish the course by exploring the solution to Maxwell’s equations in free space – electromagnetic radiation. |
