L'aggiunta di Dy\/Tb aumenta la coercitivit\u00e0, ma pu\u00f2 ridurre Br. <strong>Osenc<\/strong> seleziona il grado e la composizione pi\u00f9 adatti all'applicazione.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>2) Temperatura<\/strong><br>Il calore riduce le prestazioni del magnete. Indicativamente <strong>\u22120,1%\/\u00b0C<\/strong> su Br; in prossimit\u00e0 della temperatura massima di esercizio, si rischia una smagnetizzazione irreversibile. <strong>Osenc<\/strong> prevede un margine e seleziona il grado termico adeguato (SH\/UH\/EH\u2026).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>3) Dimensioni e forma (soprattutto lo spessore)<\/strong><br>A parit\u00e0 di materiale, <strong>lo spessore lungo la direzione di magnetizzazione<\/strong> incide pi\u00f9 del semplice aumento della superficie polare, finch\u00e9 i benefici non iniziano a ridursi. Dischi, blocchi, anelli, segmenti ad arco, smussi e fori modificano tutti il percorso del flusso. <strong>Osenc<\/strong> ottimizza le proporzioni in funzione dello spazio disponibile per il montaggio.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>4) Qualit\u00e0 della magnetizzazione<\/strong><br>Assiale, radiale, multipolare, nonch\u00e9 il livello di saturazione completa. Una magnetizzazione parziale o campi esterni possono penalizzare le prestazioni. <strong>Osenc<\/strong> test di produzione per verificare una magnetizzazione effettiva e stabile.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>5) Circuito magnetico e ambiente circostante<\/strong><br>Il traferro \u00e8 il principale nemico di #1: rivestimenti, rugosit\u00e0 e polvere generano microdistanze che influiscono sulle prestazioni. L'acciaio del pezzo deve essere <strong>sufficientemente spesso<\/strong> da non saturarsi. Il ferro di ritorno e i gioghi chiudono il circuito e concentrano il flusso. La presenza nelle vicinanze di acciaio, schermature o campi modifica il punto di lavoro. <strong>Osenc<\/strong> pu\u00f2 modellare tutti questi fattori.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>6) Distanza<\/strong><br>Il campo diminuisce rapidamente con la distanza, approssimativamente secondo <strong>~1\/r\u00b3<\/strong>. A few millimeters matter. <strong>Osenc<\/strong> designs to squeeze that effective gap down.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>7) Surfaces &amp; assembly<\/strong><br>Flatter, smoother, more parallel = more force. Thick coatings = extra gap. Chips\/cracks reduce effective volume. <strong>Osenc<\/strong> machining and finishing keep these in check.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>8) Stacks &amp; arrays<\/strong><br>Stacking along the magnetization \u2248 making it \u201cthicker,\u201d but gains aren\u2019t linear. <strong>Halbach<\/strong> arrays can make one side super strong and the other side quiet. <strong>Osenc<\/strong> can design arrays for tight spaces.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>9) Process &amp; tolerances<\/strong><br>Sintering density, grain alignment, recipe control, and dimensional tolerance all drive batch-to-batch consistency. <strong>Osenc<\/strong> focuses on stable, repeatable production.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>10) Environment &amp; lifetime<\/strong><br>Moisture\/salt spray corrodes; long-term heat, external fields, and shock degrade performance. Use NiCuNi, Zn, epoxy, or full encapsulation as needed\u2014<strong>Osenc<\/strong> recommends coatings per environment.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Confronto delle prestazioni magnetiche<\/h2>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"600\" src=\"https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/09\/Neodymium-Magnet3.webp\" alt=\"Quanto \u00e8 potente un magnete al neodimio\" class=\"wp-image-6224\" srcset=\"https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/09\/Neodymium-Magnet3.webp 800w, https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/09\/Neodymium-Magnet3-600x450.webp 600w, https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/09\/Neodymium-Magnet3-768x576.webp 768w, https:\/\/ct.semitanker.com\/wp-content\/uploads\/2025\/09\/Neodymium-Magnet3-16x12.webp 16w\" sizes=\"(max-width: 800px) 100vw, 800px\" \/><figcaption class=\"wp-element-caption\">ball<\/figcaption><\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Ferrite Magnets<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">People ask, &#8220;how strong are <a href=\"https:\/\/ct.semitanker.com\/it\/neodymium-magnets\/\" target=\"_blank\" rel=\"noreferrer noopener\">magneti al neodimio<\/a> compared to ferrite?&#8221; Neodymium magnets are up to 20 times stronger for their size.

Here are some fun ways I use Osenc\u2019s micro and large magnets to see their power in action:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Test Tube Bubble Trick<\/strong> \ud83e\uddea: I fill a test tube with alcohol and watch what happens when I bring a neodymium magnet close. The air bubble inside moves! This shows how the magnet affects the liquid, even without touching it.<\/li>\n\n\n\n<li><strong>Manganese Solution Attraction<\/strong> \ud83d\udca7: I mix a 25% solution of manganese (II) chloride in ethanol. When I hold a strong Osenc magnet near the test tube, the liquid moves toward the magnet. This shows how some liquids can be pulled by a magnet.<\/li>\n\n\n\n<li><strong>Liquid Surface Shape<\/strong> \ud83e\uddf2: I place a neodymium magnet above a test tube filled with liquid. The surface of the liquid forms a little hill, pulled up by the magnet\u2019s force. It looks like magic, but it\u2019s just science!<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Tip: I always use gloves and keep my fingers away from the magnets. Neodymium magnets snap together fast and can pinch hard!<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">Visualising Pull Force<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>How do I see the pull force of a neodymium magnet?<\/strong> I use simple tools and tricks to make the invisible force visible. Here are my favorite ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Iron Filings Magic<\/strong> \u2728: I sprinkle iron filings on a piece of paper and slide an Osenc magnet underneath. The filings line up and show the magnet\u2019s field. It looks like a spiky pattern!<\/li>\n\n\n\n<li><strong>Water Flow Test<\/strong> \ud83d\udca6: I fill a clear container with water and move a big Osenc magnet near the side. Sometimes, I see the water swirl or tiny bubbles move. The magnet\u2019s pull can even change how water flows.<\/li>\n\n\n\n<li><strong>Compass Reaction<\/strong> \ud83e\udded: I place a compass near a neodymium magnet. The needle jumps and spins, showing how strong the magnet\u2019s field is. It\u2019s a cool way to see magnetic power in action.<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">Note: I always keep magnets away from electronics and medical devices.
