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