In this paper, we use the wave equation of charged mass point to prove the existence of magnetic monopole. And according to Rubakov-Callan model there could be a lot of magnetic monopoles in neutron stars. Then using the structure equation of neutron stars we obtain upper limit and lower limit of mass-radius ratio for magnetic charged neutron star.
