I magneti a ciambella al neodimio BMAG sono caratterizzati dalla loro distintiva apertura centrale ampia e dalle robuste pareti esterne. Spesso definiti \u201cmagneti con foro\u201d, questi componenti a forma di ciambella sono la soluzione ideale per i progettisti che necessitano di integrare magnetismo ad alta resistenza con elementi di fissaggio meccanici come bulloni, viti o alberi. La forma a ciambella consente una distribuzione unica del flusso che \u00e8 particolarmente efficace per assemblaggi in stile \u201csandwich\u201d in cui il magnete viene bloccato tra due piastre d'acciaio.<\/p>\n

Nonostante la rimozione del materiale centrale, questi magneti mantengono un elevato rapporto volume-resistenza. Ottimizziamo il circuito magnetico concentrandoci sul \u201ccoefficiente di permanenza\u201d (Pc), garantendo che la geometria a ciambella non porti all'autodemagnetizzazione. Disponibili in vari spessori, questi magneti possono essere personalizzati con fori svasati o alesature dritte. I bordi lisci e smussati impediscono al fragile materiale al neodimio di scheggiarsi durante il fissaggio ad alto impatto, mentre la placcatura multistrato garantisce una superficie a basso attrito per una pi\u00f9 facile manipolazione durante il processo di assemblaggio.<\/p>\n

BMAG Neodymium Donut Magnets are characterized by their distinctive wide-center aperture and robust outer walls. Often referred to as “hole magnets,” these donut-shaped components are the ideal solution for designers who need to integrate high-strength magnetism with mechanical fasteners like bolts, screws, or shafts. The donut shape allows for a unique flux distribution that is […]<\/p>\n","protected":false},"featured_media":3610,"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":[36,15,105,111,123],"product_tag":[],"class_list":["post-3609","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","product_cat-speaker","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/product\/3609","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/comments?post=3609"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/media\/3610"}],"wp:attachment":[{"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/media?parent=3609"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/product_brand?post=3609"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/product_cat?post=3609"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/www.bmagmagnet.com\/it\/wp-json\/wp\/v2\/product_tag?post=3609"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
