Abstract

The article considers the Ponderomotive forces acting on non-closed Foucault conduction currents in a symmetric conductor. The example of a symmetric conductor located in an axially symmetric, external alternating magnetic field being given. These currents are closed by displacement currents, which are affected by the magnetic field of conduction currents in a conductor producing the Abraham force. It is shown that the alternating magnetic field created by the displacement currents has no effect on the conduction currents in the conductor. The only magnetic force, the average value of which for the period of oscillations of the external magnetic field is not equal to zero, is the self-action force with which the conductor acts on itself. The sum of Abraham`s forces and self-action is equal to zero which corresponds to the law of conservation of momentum. The traction force, the role of which is played by the self-acting force is maximal at the greatest inhomogeneity of the source of the external variable field at its periphery.
