Magnetic fields are known to play a fundamental role in stellar evolution but the magnetic properties of massive and intermediate-mass stars are not well understood. Only a small (7%) fraction of massive and intermediate-mass stars are found to be magnetic and their dipolar magnetic field strength is above ~300 Gauss. The current paradigm, the fossil field theory, describes this magnetism as remnant of an early phase of the star-life, but leaves many basic questions unanswered, such as the small fraction of magnetic stars, and in practice provides no constraint to stellar evolution theory. Recently, an ultra weak magnetic field (less than 1 Gauss) has been discovered in two intermediate mass stars (Vega and Sirius). They may be the first de...
