The expression for the free energy of arbitrary perturbations of general Vlasov-Maxwell equilibria derived by Morrison and Pfirsch is transformed and put in a concise form, which is subsequently evaluated for arbitrary, double-symmetric equilibria in the case of internal perturbations, that is perturbations which vanish outside the plasma, and on its boundary. With the single exception of the configurations in which the equilibrium distribution functions are everywhere isotropic and monotonically decreasing functions of the particle energy, these equilibria always allow negative-energy perturbations, without requiring a large spatial variation of the perturbation across the equilibrium magnetic field.
