Motivated by the Fermi observations of someγ-ray pulsars in which the phases of radio andγ-ray peaks are almost the same,we investigate the outer gap model in a retarded dipole with a current-induced magnetic field and apply it to explain pulsedγ-ray properties of the Crab pulsar.Our results show that the observedγ-ray energy-dependent light curves,which almost align with the radio light curve and phase averaged spectrum for the Crab pulsar,are reproduced well.
