Abstract: Simplicity and more intelligence in its functionality are key features of the Magneto Rheological Fluid (MRF) technology. This technology is an old “newcomers” coming up rapidly on the research and commercial front. In this paper, Magneto Rheological fluid samples are prepared. In this, silicone oil is used as a carrier fluid and is mixed with micron sized iron particles. In order to reduce the sedimentation, white lithium grease is also mixed as an additive in the fluid sample. An experimental setup consisting of an electrical stirrer with speed control unit is designed and developed and fabricated for preparation of the fluid samples. The observations of the surface morphology of iron particles were carried out using digital scanning electron microscope (SEM). The sedimentation properties are studied by visual inspection. The off-state rheological properties e.g. viscosity and shear stress variation with respect to shear rate of the fluid samples are investigated and are measured with a rotational rheometer.
