Superparamagnetic nanoparticles are widely applied in separation technologies, however, their collective behaviour in magnetic fields is poorly understood. We fill this gap by investigating the pattern formation due to magnetic non-linear interactions between spherical particles in static and dynamic homogeneous fields. The interplay between thermal fluctuations, magnetic attraction and repulsion as well as hydrodynamic friction yield a wealth of surprizing and interesting patterns. Our work is mainly experimental but we propose some theoretical ideas as well. Last but not least we explain some biotechnological applications of our results.
