    • Abstract

       

      Bianchi type-I massive string cosmological model for perfect fluid distribution in the presence of magnetic field is investigated in Rosen’s [Gen. Relativ. Gravit. 4, 435 (1973)] bimetric theory of gravitation. To obtain the deterministic model in terms of cosmic time, we have used the condition $A = (B C)^n$, where n is a constant, between the metric potentials. The magnetic field is due to the electric current produced along the 𝑥-axis with infinite electrical conductivity. Some physical and geometrical properties of the exhibited model are discussed and studied.
