Abstract

A tensor form of the virial theorem appropriate for configurations in hydromagnetic equilibrium is obtained. Various elementary consequences of this theorem are derived such as the impossibility of spherical symmetry for static configurations with prevailing magnetic fields. A variational form of the virial theorem governing small departures from an initial static state is obtained; and the usefulness of this variational form for estimating the characteristic periods of oscillation of a hydromagnetic system is illustrated by considering a special case.
