Magnetorheological (MR) fluids belong to a family of rheological materials that undergo rheological phase change under the application of magnetic field. This paper presents a review on applications and demerits of MR fluids in engineering applications. MR fluid confines its ability only to fewer applications because of its defects and failures. The most significant demerit is sedimentation of particles which origins the formation of hard cake, making re-dispersion of particles difficult. On the other hand clumping effect occurs when higher magnetic field is applied to the MR fluid for longer period of time resulting in the separation of magnetic particles from carrier fluid and this clumping problem leads to fluid particle separation (FPS).Another failure is oxidation of particles, which weakens the magnetizing ability of the particles
