ABOUT FORCES, ACTING ON RADIATING CHARGE

It is shown, that the force acting on a radiating charge is stipulated by two reasons Å owing to exchange of a momentum between radiating charge and electromagnetic ˇeld of radiation, and also between a charge and ˇeld accompanying the charge. It is well known that the charged particle moving with acceleration radiates, and as a result an additional force (apart from the external one, F0) Å force of radiation reaction acts on it. In the present paper it is shown that this force (we shall call it as a self-action force or simply by self-action) is a sum of two parts: the ˇrst force is due to the exchange of the momentum between a particle and radiation ˇelds, i. e., the ˇelds, which go away to inˇnity. For the second force in the exchange of a momentum the ˇelds, accompanying a charge participate as well. These ˇelds do not go away to inˇnity, i. e., at inˇnity they have zero?ux of energy (details see below). We shall start with the momentum conservation law for a system of charge and electromagnetic ˇeld [1, 2] d d
