METHOD AND APPARATUS FOR MANUFACTURING 1D AND 2D MULTIPOLE MAGNET ARRAY'S

摘要

The invention relates to a magnet (101), wherein the magnet (101) has a top surface (104), a bottom surface, and a circumferential surface (105, 106), wherein the top surface (104) and the bottom surface are parallel to one another, wherein the circumferential surface (105, 106) is perpendicular to the top surface (104) and the bottom surface, wherein the magnet (101) comprises magnetic particles having a preferential direction of magnetization, wherein the preferential direction of magnetization of a first magnetic particle at the top surface (104) is essentially perpendicular to the top surface (104), and wherein the preferential direction of magnetization of a second magnetic particle at the circumferential surface (105, 106) is essentially perpendicular to the preferential direction of magnetization of the first magnetic particle. The magnetic array according to the invention contains a first sort of magnets having a north pole at the top surface and a second sort of magnets having a south pole at the top surface, and the first and second sort of magnets are mounted on a support to form a line of magnets having alternating poles at the top surface.
