Some cylindrically symmetric inhomogeneous viscous fluid cosmological modelswith electro-magnetic field are obtained. To get a solution a supplementarycondition between metric potentials is used. The viscosity coefficient of bulkviscous fluid is assumed to be a power function of mass density. Withoutassumin g any {\it ad hoc} law, we obtain a cosmological constant as adecreasing function of time. The behaviour of the electro-magnetic field tensortogether with some p hysical aspects of the model are also discussed.Comment: 17 pages, 1 figur
