Abstract
We consider a magnetic cylindrically symmetric universe with two degrees of freedom in the presence of an electrically neutral viscous fluid. The sour ce of the magnetic field is an electric current along the x-axis. The coeff icient of bulk viscosity is assumed to be a power function of the mass dens ity. Without assuming any adhoc law, we obtain a cosmological constant as a decreasing function of time which is supported by results from recent supe rnovae observations.
