Given a magneric field B=-∇&ggr; with &ggr; expanded in spherical harmonics, it is shown that analytic Euler potentials may be derived for B if &ggr; is asymmetrical but contains only the contribution of a single index n. This work generalizes a result for sectorial harmonics with n=m, derived by Willis and Gardiner (1988).
