The books by Slater (one of the great professors at MIT) are known by the low sophistication of formalism combined with a deep physical insight, apparent in the way problems are solved, using analogies, clever simplifications, numerical estimates, etc. It's physics, Fermi style. Though the theory is very sound, it is in the problems that the book excells. If you work through them, you're done with electromagnetism, and you'll love it forever.
