LRS Bianchi Type-I Magnetized Dark Energy Cosmological Model in Bimetric Theory of Relativity with Cosmological Term – Λ

In this paper, to study Locally Rotationally Symmetric (LRS) Bianchi type-I magnetized dark energy cosmological models with cosmological constant - , we have calculated Rosen,s field equations for LRS Bianchi type -I spacetimes in the presence of dark energy and discuss their geometrical as well as physical significances using two cases (i) (ii) . To obtain the determinate solution of the model, we considered i) scalar expansion is directly proportional to share ii) . In the presence of a magnetic field for the conditions , scalar expansion attains its minimum and increases with increase in indicating that the universe is expanding with increment in , for the case scalar expansion attains its maximum and decreases with increase in indicate that slows down the rate of expansion.
