Introduction to Electrodynamics

>Griffiths Yes! I actually jumped in this thread to recommend Griffiths' Electrodynamics. Even the review sections on how to think about things like divergence and curl is particularly well done by Griffiths.

Introduction of Quantum Mechanics and Introduction to Electrodynamics, both by David J. Griffiths. He also wrote Introduction to Elementary Particles, but I have not read that one. Both books masterfully take exceptionally complex fields and break them down into easily digested chunks, with a clear progression of ideas as you go through the book. Do note that these are "Introduction" books written for Junior/Senior Physics majors.
