Abstract
The rate of concentration equilibrium settling in the gravity field is studied for a suspension of magnetic particles. In the absence of an external magnetic field the relaxation time taking into account the co ntributions from both diffusion and dynamic sedimentation modes is eva luated. The dependence of this quantity upon the suspended particle si ze turns out to be non-monotonic with distinctive maximum lying exactl y in the size range = 100 angstrom which is characteristic to magnetic colloids.
