Abstract
A block of magnetized material for adjusting and correcting a magnetic field produced by a magnet provides adjustable correction by modifying the orientation of the magnetic moment of the block with respect to the field. A device which includes an intermediate member rotatably mounted in an orientable support and a fixing member rotatably mounted in the intermediate member makes it possible to orient a preferred direction of the block in a predetermined direction. This results in modification of magnetic disturbances produced by the block in the zone of interest of the magnet. Quantization of pointing of the orientable support is obtained by means of graduated index marks on the support, on the intermeidate member and on the fixing member.
