What is a good textbook for Intermediate E&M with challenging problems?

[nsatya]

Does anyone know of a good textbook with challenging problems for Intermediate E&M? The one we are using in my class is "Introduction to Electrodynamics" 3rd ed. by Griffiths. I looked at the problems in the book, and they don't seem to be hard enough. I'm not really looking for problems that are more math-intensive, but problems for which the basic concept needs to be applied to a difficult application. Does anyone have a suggestion?

You looked at the problems, and they don't seem to be hard enough. But have you actually tried them? I think there certainly are a few exercises in there which require pretty good thinking.

But of course, you can always look at other textbooks (at the same or higher level), like Jackson, Vanderlinde, Greiner. You may also want to take a look at this (the corresponding textbook - without exercises - is also good).
