Title (EN) MAGNETIC ARRAY FOR SECURING AN OBJECT TO A FERROMAGNETIC SURFACE
(FR) MATRICE MAGNÉTIQUE POUR FIXER UN OBJET À UNE SURFACE FERROMAGNÉTIQUE
Abstract:
(EN) A magnetic array for attaching an object (14) to a ferromagnetic surface includes a plurality of magnets arranged in a matrix (20), the plurality of magnets being attached to one surface (22) of the object. Each magnet (20a) in the plurality of magnets has an opposite polar orientation from a magnet immediately adjacent (20b) in the matrix along a row or a column of the matrix. The plurality of magnets produces more magnetic holding force than that of a single magnet of comparable size or mass. The magnetic field of the plurality of magnets is also more closely bound to a surface of the plurality of magnets, thus the magnetic field decays more quickly moving away from the matrix than the magnetic field of a single magnet of comparable size or mass.
(FR) L'invention porte sur une matrice magnétique pour fixer un objet (14) à une surface magnétique, la matrice magnétique comprenant une pluralité d'aimants agencés en une matrice (20), la pluralité d'aimants étant attachés à une surface (22) de l'objet. Chaque aimant (20a) de la pluralité d'aimants a une orientation polaire opposée à celle d'un aimant immédiatement adjacent (20b) dans la matrice le long d'une rangée ou d'une colonne de la matrice. La pluralité d'aimants produit une force de retenue magnétique supérieure à celle d'un seul aimant de taille ou de masse comparable. Le champ magnétique de la pluralité d'aimants est également plus étroitement limité à une surface de la pluralité d'aimants, donc le champ magnétique décroît plus rapidement en s'éloignant de la matrice que le champ magnétique d'un seul aimant de taille ou de masse comparable.
