A new class of plane-symmetric inhomogeneous cosmological models of perfect
fluid distribution with electromagnetic field is obtained. The source of the
magnetic field is due to an electric current produced along the z-axis. F12
is the non-vanishing component of electromagnetic field tensor. The free
gravitational field is assumed to be of Petrov type-II non-degenerate. We have
studied three cases : (i) cosine hyperbolic (ii) linear and (ii) cosine form.
Some geometric and physical properties of the models in the presence and absence
of magnetic field are also discussed.
