Hall current effect on magnetohydrodynamic waves in rotating liquids

Abstract

The effect of the Hall current on the directional distribution and attenuation of waves created by a localised periodic source in ionized, incompressible, rotating liquids in the presence of a uniform externally applied magnetic field has been studied using a technique developed by Lighthill1). It is found that the Hall current causes a radialexpansion of Alfven waves and radialcontraction of Taylor waves**). It also alters the modes of decay of these waves.
