The optogalvanic detection of the magnetic resonance on the Helium ( 23S 1) metastable state is investigated in view of its application to 4He magnetometers. Metastable atoms are optically pumped with an intensity modulated beam and resonance signals are measured versus geometrical such as light polarization and magnetic field orientations.
