RESUMO
Recently, Saleem and Haque [Phys. Rev. E 60, 7612 (1999)] concluded that in the presence of a perturbed electron current parallel to an external magnetic field, the dispersion relation of the electrostatic convective cell and the magnetostatic modes is not modified. In the present Comment, the properties of electromagnetic as well as electrostatic waves in a nonuniform dusty magnetoplasma are reexamined, to demonstrate that Eq. (13) of the paper by Saleem and Haque as well as their conclusions are erroneous.
