Flow and properties of suspensions of magnetic nanoparticles - commonly called magnetic fluids or ferrofluids - can significantly be controlled and influenced by the action of weak magnetic fields with a strength below 100 mT. This makes them an interesting medium for various investigations in hydrodynamic research. In particular transport phenomena like the transport of heat, momentum or matter will depend qualitatively as well as quantitatively on the strength and direction of magnetic fields applied to the magnetic fluids under investigation. Due to the usual technique for generation of variable magnetic fields by means of solenoids - providing a homogeneous axial magnetic field - or straight current leading wires - generating an azimuthal field with radial gradient - such investigations are preferably carried out in cylindrical geometry (see Fig. 1), matching the geometry of the magnetic fields applied.
