The use of magnetic functional fluids changes in damping force of a damper without using many complicated mechanisms. In this study, magnetic functional fluids having both micrometer- and nanometer-sized magnetic particles are used in the damper. Four magnetic functional fluids having different material and shape of micrometer-sized magnetic particles are used in the experiments. Damping forces of each damper using the magnetic functional fluids are measured under constant frequency of vibration and constant or variable applying magnetic field. It is shown that the damping force under non magnetic field, increase rate of the maximum damping force by applying magnetic field and response of the damping force under variable magnetic field.
