The aim of this article is to carry out analysis to enhance the performance of the ferro fluid lubricated porous step bearing. The porous coating is assorted to the lower flat impermeable surface. A step is there in upper surface which approaching to lower surface. This study considered that magnetic field is flexible and oblique to the lower surface. By considering Jenkins Model, expressions for pressure and load capacity are obtained. The non-dimensional load capacity is also calculated for various parameters. Based on results, it is observed that load capacity increases if suitable step size is considered. Also, comparison between R. E. Rosensweig Model and Jenkins Model is carried out. Finally, it is advised to design a porous step bearing, one should consider Jenkins Model over R. E. Rosensweig Model.
