Abstract
By exploring the gasdynamical model of an interstellar medium threaded by a uniform magnetic field in which internal motions are dominated by thermal electrons governed by electromagnetic induction with Hall's component of the electric field we found that such a medium can support wave transport of magnetic flux density. The propagation of this circularly polarized helicoidal wave in the direction of the background magnetic field is accompanied by coherent oscillations of the densities of the electron current and the magnetic flux. We argue that these magneto-electron waves can produce a sizable contribution to the broadening of interstellar molecular lines.
