The aim of this paper is review the viscosity of magnetorheological (MR) fluid as function of shear rate. The different rheological models of shear stress as a function of shear rate have been reviewed. MR fluid has been characterized at various shear rates for different magnetic fields to observe the shear behavior of MR fluid. In order to confirm the shear behavior of MR fluids, experiments have been conducted in MR brake test rig. The results show that with increase in shear rate, there is decrease in braking torque.

Keywords: MR fluid, MR brake, Shear behavior
