Resumen:
We consider the electromagnetic field of a charge moving with a constant acceleration
along an axis. We find that this field obtained from the Li´enard–Wiechert potentials
does not satisfy Maxwell equations if one considers exclusively a retarded interaction.
We show that if and only if one takes into account both retarded interaction and direct
interaction (so-called “instantaneous action at a distance”) the field produced by an
accelerated charge satisfies Maxwell equations.
