Iron-nitride magnetic fluid has higher magnetization compared with water-based magnetic fluid W-40 or kerosene-based magnetic fluid HC-50 that are usually used. The effects of magnetic field on oscillation characteristics of a flat plate in iron-nitride magnetic fluid are investigated experimentally and compared with the case of other magnetic fluids especially taking into account the viscous effect. It is clarified that the iron-nitride magnetic fluid has relatively large viscous effect on damping characteristics compared with the commercial magnetic fluids.
