Abstract : This paper, devoted to a Bianchi Type-V anisotropic model of the universe within framework of f (R, T) gravity, considering a bulk viscous fluid as the matter in the presence of an electromagnetic field. Field equations corresponding to the chosen metric are derived and solved under suitable physical assumptions relating the expansion scalar to the shear scalar. By evaluating the physical parameter, we examine the effect of matter and electromagnetic field on universe expanding nature.

Keywords : Bianchi Type V Model, Bulk Viscous Fluid, Electromagnetic Field, Modified Theory of Gravity.
