The capture of fine paramagnetic particles from a fluid suspension in a magnetic filter element of novel design is analysed. Unlike the systems previously analysed, in our model the flow is bounded by two parallel planar plates and the ferromagnetic wires are installed outside this space, within a plane parallel with the plates. Our analysis is based on the study of particle trajectories taking into account both the laminar and the potential flow of the carrier fluid. For these we establish the capture cross-section and the conditions for the maximum recovery of the particles in suspension. This study is useful in designing magnetic filter batteries with corrosion-protected ferromagnetic wires.
