It is shown that magnetic forces as the force -/+ mu(V) over barB, exerted on electron spins at rest, account for both the transverse spin imbalance typical of spin Hall effect and the transverse charge imbalance associated with pure spin currents (inverse spin Hall effect). Considering that for stationary currents the laboratory reference frame, and those for which the spin up and spin down carriers are at rest, are inertial systems one can easily find the forces exerted by the lattice on both spin sub-bands, as well as the force between sub-bands.
