Abstract

The Magnetic, yield and rheological properties of the Magnetorheological (MR) fluids are discussed. Based on the microstructure of a magnetic chain a theoretical model was developed to analyze the effect of the applied magnetic field on the yield stress of the MR fluids. A bingham model was used to describe the rheological characteristics of the MR fluids subject to an applied magnetic field. The results show that the MR fluid exhibits super paramagnetic behavior. The yield stress increases as the applied magnetic field increases. The MR fluids can be used in clutch, valve, and damper devices because the yield stress of these fluids can be continuously adjusted by the applied magnetic field.
