The textbook my Emag professor wrote himself made sure to avoid anything intuitive or visual, and was just a dense tome of text and equations with nothing else. He had a lot of trouble getting it published, but made sure to teach from it for decades. If you asked nicely, he'd give you a copy of the errata that he never fixed in the book. That class was essentially "vector calc for EEs" so it was my introduction to all these concepts, and I never intuitively understood them until much later.
