>>11222217Well it depends on what you currently know. Do you know vector calculus and differential equations? If so you pretty much have most of the maths you'll need. Then start with electrostatics and then move to electrodynamics. The textbook we used in my undergrad was Field and Wave electromagnetics by David Cheng. I quite liked it. I haven't done electrical machines so another anon will have to help with suggestions for that but googling will get you through a lot.
tldr; read textbooks
