Dynamical equations for the plasma in a toroidal confinement system with a magnetic field which varies rapidly over space are derived in the MHD approximation. These equations are averaged over the longitudinal coordinate. They simplify the problem substantially, reducing it to a study of an axisymmetric equilibrium. This procedure is used to solve the problem of the equilibrium and stability of a plasma in a toroidal stellarator which lies in a plane. A condition is derived for the occurrence of the flute instability. It is shown that the stability of the plamsa can be improved by raising the pressure; i.e., a self-deepening magnetic well may form.
