| Abstract: | The equations of motion of a magnetic field aligned column of ionization embedded in an unbounded weakly ionized plasma immersed in an external electric field E are solved to second order terms in the strength of the initial perturbation, which is assumed to be weak. It is shown that when the Hall currents induced by the internal electrostatic field are taken into account, the centre of mass of the column will, in general, move along a curved path before acquiring the familiar drift velocity. |
