The method involves providing the magnet system with a magnetizing coil (22) and applying a current pulse to the coil of limited pulse duration to create a magnetic field that interacts with the magnet system. The pulse duration of the current pulse is limited to a value between 10 microseconds and 500 microseconds, preferably between 10 and 200 microseconds. Independent claims are included for the use of the method to magnetize permanent magnets made of rare-earth materials; and for an apparatus for magnetizing a magnet system.
