Abstract

This work studies the ponderomotive forces occurring in liquid conductors with macroscopic inclusions. It is shown that if the electric conductivity of inclusions is higher than the electric conductivity of the host medium then the inclusions are attracted to the axis of a conductor. In the opposite case the ponderomotive forces repel the inclusions towards the surface of a conductor. It is shown that if a certain relation between an amplitude and a frequency of an electric current is satisfied, the parametric resonance in the oscillations of the inclusions with electric conductivity higher than that in the bulk of the conductor can occur. The moments of the ponderomotive forces exerted on a particle of a nonspherical shape are determined. It is shown that the direction of the moment of a ponderomotive force alternates depending upon the sign of the difference between the electric conductivity of an inclusion and of the host medium.
