In order to enhance the lubricating capacity of the magnetic lubrication on the surface of the porous material, a new magnetic lubricating field has been designed by simulating method based on the coupling relationship between the pores and micro-magnets structure. The results show that the output characteristics of magnetic fluids in the pores of the material play a significant role in the design, whereas the output characteristics depend on micro-magnets and the pores’ size such as length and diameter, for example, when the ratio of length/diameter of the pore is larger than 3.2 ,the output capacity of the magnetic fluids in the pores presents a stable value, but when the ratio is smaller than 3.2, the output capacity obviously decreases. It is also found when the distance among the pores changes from 5 mm to 8 mm, the output capacity also presents a stable value; however, the output capacity obviously decreases with the increased distance among the pores beyond 8 mm. Furthermore, the effect of the parameters of micro-magnets structure on the output capacity of magnetic fluids is also investigated in the paper. The research results are helpful to improve the lubricating properties of the magnetic fluids on the surface of the porous material.
