A magnetic assembly which may be incorporated in a bracelet which can be worn on the wrist for applying a magnetic field to a subject includes an inner cylindrical magnet 1 having opposing magnetic poles disposed at respective first and second faces 2 and 3. A cup-shaped ferrous metal housing 4 forms a magnetic shield around the inner magnet enclosing the second face 3, with an end face 7 continuously surrounding the first face 2 of the inner magnet. A ring magnet 8 surrounds the inner housing 4 with opposing magnetic poles disposed at respective first and second faces 9 and 10 with the first face 9 surrounding the end face 7 of the housing. The ring magnet 8 is enclosed within a further ferrous metal housing 11 forming a magnetic shield around the ring magnet and enclosing the second face 10. The further housing 11 has an end face 14 which continuously surrounds the first face 9 of the ring magnet. The end faces of the housings 4 and 11 are proximate to the respective first faces of the inner magnet 1 and the ring magnet 8 such that these faces together form a planar magnetically active surface of the assembly for placement adjacent to the subject. |
