ABSTRACT
At dielectrophoresis, the force acting on the screened particle is different from zero, as well as the torque of the force acting on the screened particle in electro-orientation and electrorotation effects. One of these mechanisms act when the particle, polarized in the direct field, rotates and entrains slowly relaxing charges by its rotation, the latter ones participating in the formation of its induced dipole moment. The distribution of volume force, formed in the double layer of a spherical particle and dependent on the square of the nonequilibrium applied field, is of complicated dependence on the polar and azimuthal angles. The generalizations consist of consideration of the influence of the volume of electric forces acting on the liquid within the diffuse part of the equilibrium electric double layer and responsible for the change of hydrodynamic fields appearing around the polarized particle.
