Scientific paper

Bianchi Type I magnetized string cosmological model following the techniques used by Letelier and Stachel, is investigated. To get a determinate model, we assume a condition ɛ = λ (geometric string) where ɛ is the rest energy density, λ the string tension density and expansion (θ) is proportional to eigen value σ1 1 of shear tensor (σ j i ), which leads to A = ℓ ( BC) n where A, B, C are metric potentials and ℓ and n are constants. The behaviour of the model in presence and absence of magnetic field is discussed. The physical and geometrical aspects of the model are also discussed.
