The current and the magnetic moment of the nucleon are calculated, starting from a relativistic one nucleon formalism. It is shown that the relativistic corrections are very important for the current and the magnetic moment of the nucleon, especially for the vector part of the former and the scalar part of the latter, where the effects of the recoils are of the same order as those given by the static model. The numerical result, obtained by means of Chew's method, shows that the neutron current and the scalar part of the magnetic moment may be consistent with the experiment by choosing suitably the coupling constant(g^2 / 4π=0.08 or 0.10)and the cut-off momentum(k_<max>=5μ, 6μ or 7μ). However the effect of the nucleon recoil to the vector part of the moment is destructive and gives a definitely smaller value than the empirical one. It is also shown that the renormalized charge is equal to the unrenormalized charge in our approximation which contains only the terms up to the order of 1 / M.
