If you would like to learn some of the mathematics in E&M; this book is nearly perfect. For those wanting to learn physics, Feynman is the appropriate book.For example, consider the following: what is more important to you: learning how to spend time with tensors or learning why the spring model of the dipole is important?Though Jackson is regarded as a classic, if you read Feynman for the physics, and perhaps Griffiths for the problems, you will probably know what you are talking about.In short, Jackson does indeed have interesting discussions on certain topics, but overall this book focuses on terse mathematics rather than physics.
