This paper deals with the study of the effect of MHD on thin films of a micropolar fluid. These Thin films are considered for three different geometries, named: (i) flow down an inclined plane, (ii) flow on a moving belt and (iii) flow down a vertical cylinder. The transformed boundary layer governing equations of a micropolar fluid and the resulting system of coupled non-linear ordinary differential equations are solved numerically by using shooting method. Numerical results were presented for velocity and micro-rotation profiles within the boundary layer for different parameters of the problem including micropolar fluid parameters, magnetic field parameter and etc., which are also discussed numerically and illustrated graphically .
