Abstract :
Bianchi Type I bulk viscous fluid string dust magnetized cosmological model with cosmological constant term have been evaluated by solving Rosen’s field equations. The cosmological constant plays the important role and it affects the physical behavior of the model in the presence as well as in the absence of both the magnetic field and the bulk viscosity. The model is studied for the positive, negative and zero values of cosmological constant. Further in special cases, the physical and geometrical aspects of the model are studied in the absence of magnetic field and in the absence of bulk viscosity.
