In the region of developed EHD flows, the intense motion of the medium has a significant effect on current transport and convection currents may be considerably greater than ohmic conductivity currents. The electroconductive forces are collinear with the field-strength vector and are directed so as to reduce the cconductivity of the medium. The effect of electroconductive forces in nonpolar electrically insulating fluids is demonstrated in three examples. In the first two, the electric field is uniform and the effect of the dielectric component can be neglected. In the last example, the dielectrophoretic and Coulomb components are oppositely directed. In the first two, the effect of a uniform electric field on a region of heightened conductivity insulated from the electrodes is discussed; in the third, the electric wind from a point is considered.
