Gerasimov There exists an opinion accordingly which the Newton’s third law does not hold in magnetostatics. An alternative point of view doubts classical electrodynamics based on the Biot-Savart force law. This is a reason to consider the ponderomotive magnetic force by means of which a part of the closed electric circuit acts on itself. The magnitude of such a force is determined by vector potential at ends of the conductor. It is shown that in general case this force does not equal zero. The existence of self-acting is a formal approach of the modern field electrodynamics and does not contradict to conservation laws. Keywords: non-reserved system, current elements, self-force, magnetostatics. Contacts: E-mail: gsim1953@mail.ru Pp. 03-07.
