Abstract Force-field theory is studied in 3-dimension using the full diffusion tensor incorporating drift effects. An analytical approximate solution is deduced under some assumptions which include a flat neutral sheet and a non-uniform density distribution at the outer boundary. By contrast with the usual force-field theory, our solution gives a large and charge dependent latitudinal gradient and near perfect isotropy, even corotation disappears. The results are in general agreement with the numerical calculations of Jokipii and Kopriva.
