Complementing a previous work on optical forces and optical force categorizations on dipole particles having both electric and magnetic properties in the generalized Lorenz-Mie theory (GLMT), the present work provides a rigorous identification between the dipole limit of the GLMT and the dipole theory of forces (DTF) as applied to such particles. Since non-coupled force contributions from pure electric dipoles have already been recently investigated by the authors, here we focus on pure magnetic non-coupled and electric-magnetic coupling forces, the former being identified by means of the T-transformation recently presented by the authors, while the latter uses reduced partial wave expansions of the GLMT-derived during previous analysis of pure electric forces-to express the incident fields in the DTF in terms of beam-shape coefficients.
