Hello, I just had a quick question. Does anyone have links to online lectures for Upper-Division Electromagnetism? I so far haven’t been able to find much other than a few isolated videos here and there. I’m looking for something that covers Legendre polynomials, spherical harmonics, maxwell’s equations, etc. My professor unfortunately isn’t very good at lecturing since he’s primarily a scientist at LBNL. Any help would be greatly appreciated.
