摘要：
Cylindrically symmetric inhomogeneous string cosmological model in presence of electromagnetic field is investigated. We have assumed that F-12 is the only non-vanishing component of F-ij. The Maxwell's equations show that F-12 is the function of x alone whereas the magnetic permeability is the function of x and t both. To get the deterministic solution, it has been assumed that the expansion (theta) in the model is proportional to the eigen value sigma(1)(1) of the shear tensor sigma(i)(j) The physical and geometric aspects of the model are also discussed.
