Abstract

In this paper in the presence of Magnetic field, LRS Bianchi Type I string dust cosmological models in Rosen’s bimetric theory of gravitation is investigated.  Also its nature is discussed in the absence of magnetic field.  To deduce a determinate solution, the condition  A = lBn where  l  and n are real constants, between the metric potentials is used.  Special model is investigated by introducing the transformation .Further the Physical and geometrical significance of the model are discussed.
