Abstract
The invention relates to a magnet configuration with permanent magnets (5, 6) around a yoke (2, 3, 4) connecting these permanent magnets (5, 6). The magnetic field strength of this magnet configuration is varied thereby that in the region of the yoke (2, 3, 4) at least one rotatable body (8) is provided which comprises at least two spatially separated materials (9, 10) with different magnetic properties.
