A general solution for force-free magnetic fields in spherical coordinates

Abstract

This paper shows that there is a solution for the vector Helmholtz equation in spherical coordinates that does not fit in the: general expression given by Hansen [l], Stratton [5] and Chandrasekhar and Kendall [2]. This paper finds a more general solution of the vector Helmholtz equation in spherical coordinates. This is applied to force-free magnetic fields in spherical coordinates.
