Abstract
The paper examines the theory which ascribes the periodic reversal of magnetic field of some stars to internal oscillations. It is shown that, to get sufficiently rapid oscillations, a large internal magnetic field need not be postulated; mechanical forces unaided can always produce a sufficiently rapid oscillation. Indeed, only for a particular class of oscillations do the mechanical forces produce a sufficiently long period: in oscillations of this class the motion is shown to be mainly confined to the surface layers. Such oscillations are examined to see if they can explain the periodic reversal of the observed magnetic field. The results so far are negative, but do not cover all the possible oscillations. The problem of the maintenance of the oscillations, and other related problems, are briefly discussed.
