For an extensive treatment of the electromagnetic field and energy of a point particle at relativistic velocities, chapter 15 of Franklin's "Classical Electromagnetism" is recommended, along with chapter 12 of Griffiths' "Introduction to Electrodynamics," which covers electrodynamics and special relativity. Wolfgang Rindler's "Introduction to Special Relativity" also includes a significant section on electromagnetism, though it focuses more on special relativity. The discussion highlights the availability of resources for understanding how fields transform under Lorentz transformations, with suggestions for both straightforward and more complex scenarios. Overall, there are multiple texts available that address various aspects of electrodynamics in the context of relativistic motion.
