A mathematical model to describe the macroscopicbehaviour of an axial magnetic filter is developed. Themodel takes into account the long range of absorptionforces. Partial mixing of the particles in the fluid isincluded by introducing the concept of “mixing length”.Behaviour of an axial filter under different conditions isnumerically simulated. Experiments with colloidal ferriteparticles indicate that for an axial filter composed of 12μm steel wires with a packing factor of 4.8% the mixinglength is of the order of 4 mm.
