Abstract: The influence of heat transfer and induced magnetic field on peristaltic flow of a Johnson-Segalman fluid was studied. The purpose of the present investigation was to study the effects of induced magnetic field on the peristaltic flow of non-Newtonian fluid. The two-dimensional equations of Johnson-Segamlan fluid were smiplified by assuming a long wave length and low Reynolds number. The obtained equations were solved for the stream function, magnetic force function, and axial pressure gradient by using a regular perturbation method. The expressions for the pressure rise, temperature, induced magnetic field, pressure gradient, and stream function were sketched for variousem bedded param eters and were interpreted. -
