We have investigated homogeneous anisotropic Bianchi type IX cosmological model for perfect fluid distribution with electro-magnetic field. The magnetic field is due to an electric current produced along x axis thus 23 F is the only non-vanishing component of electromagnetic field tensor ij F . To get a determinate model, we have assumed the condition n a b = between metric potentials, where n is constant. The various physical and geometrical aspects of the model viz pressure, density, shear, expansion factor, electromagnetic field tensor and conformal curvature are also discussed.

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.
