摘要
The present study deals with Bianchi type III string cosmological models with magnetic field. The magnetic field is assumed to be along z direction. Therefore F-12 is only the non-vanishing component of electromagnetic field tensor F-ij. The expansion (theta) in the model is assumed to be proportional to the shear (sigma). To get determinate solution in term of cosmic time, we have solved the fields equations in two cases (i) Reddy and (ii) Nambu string. The physical and geometrical behaviour of these models is discussed.
