Starting from Stratton-Panofsky-Phillips-Jefimenko equations for the electricand magnetic fields generated by completely arbitrary charge and currentdensity distributions at rest, we derive far-zone approximations for thefields, containing all components, dominant as well as sub-dominant. Usingthese approximate formulas, we derive general formulas for the totalelectromagnetic linear momentum and angular momentum, valid at large distancesfrom arbitrary, non-moving charge and current sources.
