The interaction between a magnetisable fluid and an external magnetic field
gives rise to several interesting phenomena in ferrohydrodynamics. Our
mathematical models and solution strategies are mainly
focused on cases in which the magnetic liquid exhibits a free surface
which is not known a-priori. In particular, two special problems are taken
into consideration: the behaviour of a ferrofluid drop in a rotary shaft
seal and the generation of an ordered pattern of surface protuberances
when the applied field exceeds a critical value.
