If you like the abstract calculus with forms, there's a textbook about electromagnetism, which may be interesting for you:

F. W. Hehl, Y. N. Obukhov, Foundations of classical electrodynamics, Springer (2003)

Thanks, I'll check that one out! Another nice book I found that teaches similar mathematics is 'Gauge Fields, Knots and Gravity' by John Baez, which is very cool
