A plasma confined in a dipole field exhibits unique equilibrium and stability properties. In particular, equilibria exist at all β values and these equilibria are found to be stable to ballooning modes when they are interchange stable. When a kinetic treatment is performed at low beta we also find a drift temperature gradient mode which couples to the MHD mode in the vicinity of marginal interchange stability.
