An item may be provided with a body that forms an enclosure. The body (12) may have body portions (16, 18) that open and close along a seam (14). An elongated magnetic fastener (36) may run along the seam. The magnetic fastener may have first (38) and second (40) portions on opposing sides of the seam. The first and second portions may include magnets. When the magnetic fastener is operated in a closed state, the magnets in the first and second portions attract each other and pull the first and second portions of the fastener together to close the seam. When the magnetic fastener is operated in an open state, the magnets in the first and second portions repel each other and push the first and second portions of the fastener apart to open the seam.

A method for recycling at least one magnet of an electric machine. A subassembly having the magnet is disassembled from the electric machine. In the process, the following steps are provided: carrying out a first thermal treatment of the subassembly at a first temperature, mechanical separation of the magnet from the subassembly, and carrying out a second thermal treatment of the magnet at a second temperature, which is higher than the first temperature, for debinding and/or cleaning of the magnet.

An oblique angle polarized magnet includes a rectangular magnetized permanent magnet having a grain direction, an attraction surface, and a magnetic primary field line that is orthogonal to the grain direction but non-orthogonal to the attraction surface. The oblique angle polarized magnet may be used in a magnetically positioned apparatus, such as a tablet computing device cover operable as a stand for the tablet computing device. The magnetically positioned apparatus may be configured to assume a position where first and second magnets are oriented in a non-parallel orientation such that the first and second surfaces of the magnets oriented at an acute angle with respect to each other. The magnets may facilitate the position.

Each receiving groove includes a bottom wall and a side wall coupling the bottom wall. The magnetic film covers the bottom wall and the side wall of each of receiving groove.

A magnet structure comprising a plurality of individual magnets in the form of an elongate block (4) having a length (4a) extending beyond the thickness of the magnet structure. The elongate block (4) is cylindrical or polyhedral in shape with at least one flat longitudinal face (4b) orientated towards a working surface of the magnet structure, the elongate block (4) having a line of magnetisation extending along its length. The individual magnets (4) being positioned at a distance from each other in the magnet structure in order to be electrically isolated from each other, the length (4a) of each block (4) being greater than the diameter of the flat longitudinal face (4b) for a cylindrical block (4) or with a larger diagonal (4c) connecting two apexes of said longitudinal face (4b) for a block (4) in the form of a polyhedron.

Magnet array structure includes a first linear magnet array and a second linear magnet array having a first and a second arrangement of magnets, respectively, in which the first and the second arrangement of magnets are repeated along respective lengths of the first and second linear magnet array. The first and second arrangement of magnets include respective individual first and second magnet elements arranged along the respective length of the first and second linear magnet array so that no net magnetic forces parallel to the length of the first and second linear magnet array result on the first and second arrangement of magnets, respectively. The first arrangement of magnets is offset from the second arrangement of magnets so that the first arrangement of magnets and the second arrangement of magnets partially overlap.

A method for producing a permanent or soft magnet including the following steps: a) providing: a solution containing a solvent in which are dispersed a set of objects which possess a permanent magnetic moment; a substrate on which are fixed to the surface or within a cavity that it may have, a 1st pad and a 2nd pad, said 1st pad includes a face facing and parallel to a face that the 2nd pad includes; b) the solution is deposited on the surface of the substrate or, as the case may be, within its cavity; c) the substrate is placed in a magnetic field so that the set of objects are grouped together between the face of the 1st pad and the face of the 2nd pad so as to form a permanent magnet.

A two-step diffusion method for preparing high-performance dual-main-phase sintered mischmetal-iron-boron magnet belongs to the preparing technical field of rare earth permanent magnet materials. The compositions of the two main phase alloys are RE-Fe—B (RE is Nd or Pr) and (Nd, MM)-Fe—B (MM is mischmetal), respectively. First, PrHoFe strip-casting alloy is used as a diffusion source. Next, a PrHo-rich layer is uniformly coated on the surface of (Nd, MM)-Fe—B hydrogen decrepitation powders. The higher anisotropic fields of Pr.sub.2Fe.sub.14B and Ho.sub.2Fe.sub.14B are used to improve the coercivity. Then, the ZrCu strip-casting alloy is used as a diffusion source. A Zr-rich layer is uniformly coated on the surface of the powders after the first-step diffusion, which prevents the growth of the MM-rich main phase grains during the sintering process and the inter-diffusion between the two main phases, thus obtains high coercivity.

The present invention relates to the field of devices and processes for producing optical effect layers (OEL) comprising magnetically bi-axially oriented platelet-shaped magnetic or magnetizable pigment particles, in particular for producing said OELs as anti-counterfeit means on security documents or security articles or for decorative purposes. The process described herein comprises the step of a) applying on a substrate surface a radiation curable coating composition comprising platelet-shaped magnetic or magnetizable pigment particles, b) exposing the radiation curable coating composition to a dynamic magnetic field of a magnetic assembly comprising a Halbach cylinder assembly, and c) at least partially curing the radiation curable coating composition of step b) so as to fix the platelet-shaped magnetic or magnetizable pigment particles in their adopted positions and orientations, said step c) being carried out partially simultaneously or simultaneously with step b).

An adjustment apparatus for adjusting the angular tilt of a first component of a magnetic circuit relative to an alignment axis of a second component of the circuit uses at least one pair of spacers each of which has a thickness that changes continuously around its periphery. The spacers are arranged between the circuit components and, as a relative rotation between the spacers is changed, the combined thickness of the two spacers increases in one area, while decreasing in another. This results in a tilting of a top surface of the spacer pair relative to a bottom surface, and a corresponding change in a relative tilt of the first component relative to the second component. The spacers may be ring-shaped or disc-shaped, and allow for precise alignment of the magnetic circuit without the need for shims between the components.
