The ground state energy of an atom in the presence of an external magnetic filed B (with the electron spin-field interaction included) can be arbitrarity negative when B is arbitrarily large. We inquire whether stability can be restored by adding the self energy of the field, ∫B2. For a hydrogenic like atom we prove that there is a critical nuclear charge, zc, such that the atom is stable for z<zc and unstable for z>zc.
