In this paper, the phenomenon of MHD-instability of the surface equilibrium of a conductive liquid thin layer under small long-wave disturbances is investigated. The layer is under the action of electric and magnetic fields. The equations of motion and oscillation of the layer surface about the equilibrium state are presented. The equation of oscillation is investigated by the methods of the linear stability theory. A numerical analysis of the equations of motion allows to obtain some neutral curves for different values of the magnetic fields. These curves divide the region of process parameters into two domains of stability and instability for small long-wave disturbances. Figs 2, Refs 5.
