Abstract: An endeavor has been made to check and investigate the impact of surface roughness on the characteristics of squeeze film between porous annular discs is bestowed in presence of magnetic fluid. The involved Reynolds equation is solved with suitable boundary conditions and expressions for pressure and load carrying capacity are obtained. The expressions are obtained numerically and results are bestowed graphically. It is found that the load carrying capacity increase with increasing magnetization. The impact becomes more sharp when mean (-ve) is involved. In addition, standard deviation and aspect ratio decrease the load carrying capacity this negative effect is going to be minimized by the magnetic fluid lubricant in the case of negatively skewed roughness. Moreover, the investigation makes it clear that a performance of a bearing system is going to be enhanced by choosing suitable values of magnetization parameter and aspect ratio.
