The present work brings into focus the unsteady MHD two dimensional accelerating/decelerating boundary layer flows and heat transfer of an incompressible electrically conducting fluid above a moving wedge in the existence of variable viscosity. Suitable transformation is used to form a system of coupled non linear partial differential equations for governing both the flow and heat transfer. These equations have been carried out numerically, which is done by utilizing an implicit finite difference method in combination with quasilinearization technique. The obtained numerical results have been presented graphically in terms of local nusselt number, skin friction, temperature distribution, and velocity distribution for different values of magnetic field (M) and variable viscosity ($\varepsilon $) parameters along with the fixed Prandtl number (Pr) and wedge angle (m). It is found that there exist a unique solution for accelerating flow and dual solutions for decelerating flow.
