Yes, but doesn't the EM field around a moving charge contribute to its total kinetic energy due to the so-called "electromagnetic mass": https://www.feynmanlectures.caltech.edu/II_28.html ?Dale said:While the charge does have KE, that is not the energy I am talking about. I am talking about the EM field energy density: ##u=(E^2+B^2)/2## with whatever constants are needed to make the units work
