It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate them.

We also experimentally prove that this structure is a suitable device to separate beads and show that the experimental data is in good agreement with the theoretical predictions.
