The principle of magnetic fluid sealing is introduced in this paper. We design main parameters for it through a numerical computer. So the magnetic material and the design principle of its dimension are got. Also in the paper, the relationship between the single sealing pressure and angle, teeth width, sealing clearance of pole pieces are researched. Through analyzing the effect of step number on multilevel magnetic pole sealing, the optimum value range is obtained, this is beneficial to the design and the application of the magnetic fluid sealing.
