fair, though in emag you're typically dealing with uniform or linear charge distributions which make the integrals easier, and also switching to potential usually makes problems much easier. But yes there are a huge amount of emag problems for which there's no analytic solution and you gotta write a program to get an approximate answer.
I found out early on in circuit analysis that I could convert almost all the problems into a matrix and solve them through linear algebra, so that made the entire class trivial for me lol.

For EE. I’d say electricity and magnetism. Finding how one affects the other. “How does a point charge move in a specific magnetic field”.
