It is known that the effect of the boundary edge arises on the various modes in the structure and the generating number of Taylor vortex flows with low aspect ratios. In this study, our purpose is to investigate the method to control a Taylor vortex flow (TVF) with a small aspect ratio by using magnetic fluids. Flow field of magnetic fluid under the magnetic field is investigated by numerical analysis. The numerical model device has a radial ratio of 0.667, aspect ratio of 3 and the gap length between the inner and outer cylinders of 25mm. The magnetic field is applied to the flow field using coils put in electric current located on the outside of the vessel. The flow structure of magnetic fluid is controlled by the optional magnetic field
