Abstract
A theoretical study is presented of the effect of pinch induced by an axial current on the behaviour of the squeeze film of an electrically conducting lubricant between curved annular plates. The film thickness is assumed to be an exponential function of the radial coordinate. The expressions for the pressure, load-carrying capacity and squeeze time as functions of film thickness are obtained. With a convex plate configuration, axial-current-induced pinch decreases the pressure and load capacity. For a concave plate configuration the pressure increases with increase in current for large values of the dimensionless curvature parameter \\ ̄ gb while the trend is reversed for small values of \\ ̄ gb.
