The Woltjer-Taylor method is applied to spheromak plasmas in spheroidal flux con-servers. As models of the flux conserver, both oblate and prolate spheroidal vesselswith a center conductor are used. The plasma is not assumed to be nearly spherical,and the Rayleigh-Ritz method and the finite element method are used to evaluate theeigenvalues. The oblate spheromak is shown to be stable irrespective of the shape ofthe flux conserver. Though the prolate spheromak is unstable if there is no center con-ductor, it can be stable if the center conductor is installed.[spheromak, compact toroid, magnetohydrodynarnic stability, force free, ]] oblimak, prolemak, theory.l
