Les aimants tubulaires en n\u00e9odyme BMAG se caract\u00e9risent par leur longueur axiale \u00e9tendue par rapport \u00e0 leur diam\u00e8tre. Contrairement aux anneaux minces standards, la g\u00e9om\u00e9trie tubulaire offre un puits magn\u00e9tique profond et une surface beaucoup plus grande pour l'interaction de flux. Cette structure allong\u00e9e est parfaite pour cr\u00e9er des champs magn\u00e9tiques longs et uniformes le long d'un arbre ou \u00e0 l'int\u00e9rieur d'un bo\u00eetier cylindrique, o\u00f9 une s\u00e9rie d'aimants plus courts serait difficile \u00e0 aligner ou \u00e0 fixer.<\/p>\n

La conception du tube permet d'obtenir des mod\u00e8les de magn\u00e9tisation complexes, y compris une magn\u00e9tisation axiale ou diam\u00e9trale multipolaire. Les tubes longs \u00e9tant naturellement plus sensibles aux contraintes structurelles, nous utilisons un processus de frittage raffin\u00e9 qui accro\u00eet l'int\u00e9grit\u00e9 structurelle du r\u00e9seau cristallin de NdFeB. Cela r\u00e9duit le risque de fissuration longitudinale sous l'effet de la dilatation thermique. L'al\u00e9sage int\u00e9rieur est poli jusqu'\u00e0 obtenir une finition miroir pour permettre le passage sans frottement de composants ou de fluides, ce qui en fait un choix \u201cintelligent\u201d pour les syst\u00e8mes de contr\u00f4le de flux et de mouvement lin\u00e9aire de haute technologie o\u00f9 le champ magn\u00e9tique doit \u00eatre maintenu sur une plus grande distance.<\/p>\n

BMAG Neodymium Tube Magnets are defined by their extended axial length relative to their diameter. Unlike standard thin rings, the tube geometry provides a deep magnetic “well” and a significantly larger surface area for flux interaction. This elongated structure is perfect for creating long, uniform magnetic fields along a shaft or within a cylindrical housing, […]<\/p>\n","protected":false},"featured_media":3622,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[36,15,105,111],"product_tag":[],"class_list":["post-3621","product","type-product","status-publish","has-post-thumbnail","product_cat-by-coating","product_cat-by-shape","product_cat-neodymium-ring-magnets","product_cat-nickel-plated","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product\/3621","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/comments?post=3621"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media\/3622"}],"wp:attachment":[{"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/media?parent=3621"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_brand?post=3621"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_cat?post=3621"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/fr\/wp-json\/wp\/v2\/product_tag?post=3621"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
