Abstract	s: A comprehensive study of MHD two-dimensional boundary layer stagnation point flow with radiation and heat generation characteristics towards a heated shrinking sheet immersed in an electrically conducting incompressible micropolar fluid in the presence of a transverse magnetic field is analyzed numerically. The governing continuity, momentum, angular momentum and heat equations together with the associated boundary conditions are first reduced to a set of self similar non-linear coupled ordinary differential equations using similarity transformations and are then solved by a method based on finite difference discretization. Some important features of the flow and heat transfer in terms of normal and streamwise velocities, microrotation and temperature distributions for different values of the governing parameters are analyzed, discussed and presented through tables and graphs. The study reveals that the reverse flow caused due to shrinking of the sheet can be stopped by applying a strong magnetic field. The thermal boundary layers become thicker by increasing the values of the Eckert number or the heat generation parameter. Micropolar fluids exhibit a reduction in shear stresses and heat transfer rate as compared to Newtonian fluids, which may be beneficial in flow and thermal control of polymeric processing.
