In a course on electromagnetic fields & waves way back in the late 1970s, we dreamed of having our lessons illustrated with snazzy animations to help us visualize how things worked.

Do such animated lessons now exist, online & free ?

YouTube is pretty good at both theory part: there's MIT physics class, but also on intuitive parts (i.e. visualizing how phase arrays work). ChatGPT is also seems to be very good at TA/Professor job when grinding through math-heavy parts: asking intuitively explain things do wonders. And you can also ask lots of stupid questions to understand things.
