Magnetic fluid and MR fluids are representative functional fluids because their properties and characteristics can be controlled easily by applying a magnetic field. Especially, MR fluids has controllable high viscosity, high sensitivity, controllable large yield stress and strong magnetic force in the applied magnetic field due to the robust cluster formation compared with those of magnetic fluid. In the present study, two kinds of nano-MR fluids dispersed iron particle with different diameters are prepared. Vizualization of cluster formation of particles and measurements of physical properties are conducted in the low applied magnetic fields. Finally, damping characteristics of an oscillating flat plate immersed in MR fluids under the low applied magnetic fields are compared with those magnetic fluid.
