A basic experimental study was carried out to investigate the parameters in a vibration equation of a viscous damper utilizing a magnetic responsive fluid in order to design a semi-active viscous damper. We used the magnetic piston which has made with alternating layers of magnet and nonmagnetic material disks for particles of the fluids not to sediment. To clarify the damping effect, we measured a frequency response and a relationship between inertia force and displacement. The results of the dynamic characteristic of the damper can be explained by the cluster of particles aggregated like a chain in the fluid. We also clarify that MCF is suitable for the damper. The damping effect is strongly influenced by an apparent density around the piston of the damper.
