Bianchi Type-V Magnetized String Cosmological Model with Variable Magnetic Permeability for Viscous Fluid distribution

We investigate the Bianchi type-V magnetized string cosmological model with variable magnetic permeability for viscous fluid distribution. The magnetic field is due to an electric current produced along the x-axis. Thus the magnetic field is in yz-plane and F₂₃ is the only non-vanishing component of electromagnetic field tensor F_ij. To obtain the deterministic model in terms of cosmic time t, we assume the condition ξθ= const where ξ is the coefficient of bulk viscosity and θ the expansion in the model.
