Parallel static fields: energy density, vanishing Poynting flux, and the mixed-trace-free stress-energy tensor
Boost a rest four-current: lab density, three-current, invariant square, and contracted volume
Uniform-motion Liénard–Wiechert field: present-position and retarded evaluations agree at closest approach
Liénard power at fixed lab |a|: parallel versus perpendicular orientation, and the low-β limit
