摘要The locally rotationally symmetric Bianchi type-II magnetized string cosmological model with bulk viscous fluid is investigated. The magnetic field is due to an electric current produced along the x−axis. Thus the magnetic field is in the y–z plane and F23 is the only non−vanishing component of electromagnetic field tensor Fij. To obtain the deterministic model in terms of cosmic time t, we have assumed the condition ξθ=const, where ξ is the coefficient of bulk viscosity and θ is the expansion in the model.
