Abstract
A magnetic field generated by windings supported by a cylindrical former having axis Z is established in a desired direction forming an angle &PHgr; with respect to Z. Over an interval on Z, substantially constant value for the desired field and substantially vanishing orthogonal components are achieved by specifying the current distribution on the cylinder as a solution to field equations and then approximating said current distribution in a discrete conductor forming a plurality of anharmonic loops, nonlinearly spaced in accord with said solution.
