      Bianchi Type V massive string cosmological models with free gravitational field of Petrov Type degenerate in the presence of magnetic field with variable magnetic permeability are investigated. The magnetic field is due to an electric current produced along the 𝑥-axis. The $F_{23}$ is the only non-vanishing component of electromagnetic field tensor $F_{ij}$. Maxwell's equations $F_{[ij;k]} = 0$ and $F_{ij}^{ij} = 0$ are satisfied by $F_{23}$ = constant. The behaviour of the model in the presence and absence of magnetic field and other physical aspects are also discussed.
