The generation of vorticity in localized magnetic fields is explored under the low magnetic Reynolds number approximation. Analytic solutions for a creeping flow past a magnetic point dipole are obtained through a perturbation method. Also, numerical calculations for the flow past a finite size magnetic dipole are presented. It is shown that vortical structures may become unstable when inertial effects are not negligible. Figs 5, Refs 10.
