The standard scenario for evolution in a close binary system in which the neutron star pass through four evolutionary phases (isolated star, propeller, wind accretion and Roch lobe accretion) was employed to calculate transport of orbital angular momentum to the neutron star or loss of angular momentum from the whole system. The evolution of core magnetic field of neutron stars in close binary systems with a low mass main sequence companion is explored. Assuming the core as a type II superconductor so the magnetic flux can be transported as quantized fluxoids, calculation have been performed to determine magnetic filed decay and its interaction with the mater accreted from the companion. The evolution of semi major axis of the binary in a time scale of 10^9 year comparable with the main sequence life time of the low mass companion was also investigated.
