  Chiral perturbation theory is a powerful method to investigate the hadron
properties. We apply the non-local chiral effective Lagrangian to study nucleon
magnetic form factors. The octet and decuplet intermediate states are included
in the one loop calculation. With the modified propagators and non-local
interactions, the loop integral is convergent. The obtained proton and neutron
magnetic form factors are both reasonable up to relatively large $Q^2$.
