The stability of multipoles having a purely poloidal field to ballooning modes of high toroidal mode number is studied. First, a perturbation theory based on large m is discussed, and it is found that the first-order correction to the β limit is of order 1/m. Next, the equations for a linear quadrupole and octopole are solved and the results are compared with recent multipole experiments.
