In order to examine dispersion properties of magnetorheological (MR) fluids, characteristics of its medium oil such as their rheological property and density are being focused in this study. Carbonyl iron (CI) based MR fluid with an aqueous polymeric solution using poly(ethylene oxide) (PEO) as a medium was prepared. MR characteristics as a function of applied magnetic field strength was investigated using a rotational rheometer with MR devices attached, demonstrating that the characteristics of the CI-PEO based MR fluids were affected by a medium viscosity in a steady shear flow.
