Despite of the importance of magnetic fields for the full understanding ofthe properties of accreting Herbig Ae/Be stars, these fields have scarcely beenstudied over the rotation cycle until now. One reason for the paucity of suchobservations is the lack of knowledge of their rotation periods. Thesharp-lined young Herbig Ae star HD101412 with a strong surface magnetic fieldbecame in the last years one of the most studied targets among the Herbig Ae/Bestars.  A few months ago we obtained multi-epoch polarimetric spectra of this starwith FORS2 to search for a rotation period and to constrain the geometry of themagnetic field.  We measured longitudinal magnetic fields on 13 different epochs distributedover 62 days. These new measurements together with our previous measurements ofthe magnetic field in this star were combined with available photometricobservations to determine the rotation period.  The search of the rotation period resulted in P=42.076+-0.01d. According tonear-infrared imaging studies the star is observed nearly edge-on. The starexhibits a single-wave variation of the longitudinal magnetic field during thestellar rotation cycle. These observations are usually considered as evidencefor a dominant dipolar contribution to the magnetic field topology.
