DC magnets are installed for beam injection and extraction at the RCS ring in J-PARC. The four steering magnets and two septum magnets are installed at injection line in order to adjust the beam injection point. A quadratic magnet, two steering magnet and two septum magnets are installed at dump line for the part of the beam with their charge not changed from H$$^{-}$$ to H$$^{+}$$ at the charge stripping foil. Two deflecting magnets to kick out the beam without exciting the kicker magnets and three septum magnets are installed at the extraction line. Up to now, the development of the DC magnets has been finished and the field measurements are being carried out by using the 3 dimensional hole-probe with 3-axias stage and the harmonic rotating coil.
