Abstract : The radiation from PSR 0833-45 is strongly linearly polarized. Measurements at 21, 18 and 13 cm show a rotation measure of +33 + or - 5 radian/sq m. Combined with the published value of the dispersion measure this yields a mean value of 0.73 + or - 0.13 microgauss for the longitudinal component of the galactic magnetic field along the inner face of the Orion arm.
