The investigation of oscillatory flow of a magnetic fluid in a circular tube in a nonuniform magnetic field as a special case of the unsteady flow is made. It is one of the basic study on the development of damper or actuator using a magnetic fluid. Experimental study is made on the characteristics of pressure fluctuation to the given oscillatory flow. On the other hand, the theoretical analysis is made by using the equation of incompressible fluid. The experimental data are compared with the theoretical analysis, and the result shows that there is a large influence of the agglomerate of magnetic particles in a magnetic field on the resistance of oscillating flow of magnetic fluid.
