Abstract
Although the undular instabilities of a stratified horizontal magnetic field have been studied in a number of contexts we believe that the physical mechanism responsible for the instability has not been fully explained. In this paper we present a new explanation of why these instabilities occur, considering in detail the differing cases of two-dimensional and three-dimensional motions.Keywords
