The present objective is to numerically analyse the effect of induced magnetic field(IMF) of an unsteady MHD flow of Casson fluid through infinite two vertical plates. The effect of radiative heat has been scrutinized.Governing non-dimensional PDEs of the flow are discretise by finite difference method to some algebraic system of equations which is then numerically solved with respect to the boundary conditions. The effect of the radiations, magnetic Prandtl number, Prandtl number,Hartmann number and Casson parameter on temperature profile, velocity profile and on induced magnetic field have been depicted through graphs.The impact of surface drag force and the rate of heat has been influence by the parameters.
