Context. During the last decade, the FORS1 instrument of the ESO Very Large Telescope has been extensively used to study stellar
magnetism. A number of interesting discoveries of magnetic fields in several classes of stars have been announced, many of which
obtained at a 3 level; some of the discoveries are confirmed by measurements obtained with other instruments, some are not.
