The Reaction Self-Force of a Classical Point Particle Actually Does not Diverge

Authors: Kenneth Sandale

For a point charge in a uniform external electric field the laws of classical electromagnetism are currently thought to imply an infinite self-force acting on the charge, in the opposite direction of the external force. This is a physically bizarre situation. We show here that this is not actually implied by the laws of classical electromagnetism. The problem with the standard approach turns out to be that it incorrectly tacitly assumes that the self-force is generated by acceleration induced by the external field when in reality the self-force is generated by acceleration induced by the sum of the external field and the self-force field itself.
