In this work, a system for magnetic and hydrodynamic manipulation of magnetic beads is modelled.

A geometry is introduced to assure a good separation behaviour with respect to the magnetic moment of the particles. Different separation mechanisms will be discussed and an estimation of the minimal difference of separable magnetic moments will be given.

Further it will be shown, that the required magnetic fields can readily be realized.
