In this paper we study the effect of the magnetic field in string cosmology for a spatially homogenous and anisotropic Bianchi type -V space-time model. In order to study the effect of magnetic field, the standard form of the energy momentum tensor for cosmic strings is modified by including an additional term for magnetic field. The magnetic field is due to an electric current produced along the x-axis with infinite electrical conductivity. The field equations are solved for different string models such as geometric string (Nambu string), Takabayashi string (p-string) and Reddy string using string equation of state. We also find the solution for string models with uniform energy density. The physical and geometrical properties of each string model with and without magnetic field are discussed in detail.
