This paper studied the ferrofluid squeeze film, formed when the upper annular rotating plate of various shapes (viz. secant, exponential and flat) approaches the lower flat annular one normally. Expressions for pressure, load capacity and response time are obtained for a constant transverse magnetic field in each case. The results show that load capacity and response time are found to increase when the volume fraction of the particles and rotation of the upper plate increased for alI shapes of the upper plate. In the case of curvature of the upper plate, load capacity and response time are found to increase with the increase of curvature of the exponential upper plate but decreased for the secant shaped plate.
