This is an outstanding short little book on Maxwell's equations and what they mean, both qualitatively and quantitatively. It is a good book to go through if you have just finished a course on EM, or you can use it as a supplement as you go through such a course. The explanations are clear and to the point and the examples and problem sets are excellent. To me the definitive self-study textbook on the subject is&nbsp;
  
Engineering Electromagnetics







  
  
    &nbsp;by Nathan Ida. It explains everything, including the math, from the beginning. If you have an incomprehensible text and an incomprehensible professor, both these books will see you through.<br><br>Also, note the MIT lectures of Professor Walter Lewin on electricity and magnetism in his Physics 8.02 class as posted on youtube. This student guide is so clear and coincides so well with what Prof. Lewin is teaching it almost seems like it was written by him.<br><br>At any rate I can't recommend these three resources: Dr. Lewin, this student guide, and the big text by Nathan Ida strongly enough. Even if you think you're an engineer who just wants to code or design FPGA's the rest of your professional life, do realize that electricity does come back to these basics and you should understand it.
