We report the results of 6 nights of Canada-France-Hawaii Telescope spectropolarimetric ESPaDOnS observations of the He-strong, magnetic B1 type star ALS 3694. The longitudinal magnetic field is approximately 2 kG in all 6 observations, showing essen
tially no variation between nights. The H$alpha$ line displays variable emission on all nights, peaking at high velocities ($sim 3 vsin{i}$). Given the presence of a strong ($B_{rm d}>$6 kG) magnetic field, and the similarity of the emission profile to that of other magnetic B-type stars, we interpret the emission as a consequence of a centrifugal magnetosphere.
Recently announced magnetic models for four SPB and {beta} Cep stars, along with magnetic detections for two additional stars, have potentially doubled the number of known magnetic SPB and beta Cep stars (see Grunhut et al., these proceedings). We ha
ve reanalyzed the published data and re-reduced archival low resolution spectropolarimetry collected with the FORS1/2 instruments at VLT on which the models were based, and compare them with high resolution data from the ESPaDOnS spectropolarimeter at CFHT, investigating previously noted inconsistencies between results from the two instruments.
