Abstract


In this paper we have investigated LRS Bianchi type I anti- stiff fluid cosmological model with electromagnetic field and vacuum energy density. We have assumed that the magnetic field is due to an electric current produced along  z-axis. So, is the only non-vanishing component of electromagnetic field tensor Fij .To get the deterministic solution, it has been assumed that  , where p is the pressure and ρ is the rest energy density, and a relation between metric potentials , where A and B are functions of t alone. It is observed that the model has a point type singularity at  provided Physical and geometrical properties of the model are also discussed.


Keywords
