To configure this limit, refer to https:\/\/developers.cloudflare.com\/workers\/wrangler\/configuration\/#limits<\/p>\n<p><strong>1. Size and Shape<\/strong><\/p>\n<ul>\n<li>Bigger magnets generally have more pull force because they have more material producing the field.<\/li>\n<li>Shape affects how the field is distributed. For example, a thin disc won\u2019t pull the same way as a thick block, even if they\u2019re the same grade.<\/li>\n<\/ul>\n<p><strong>2. Coating<\/strong><\/p>\n<ul>\n<li>Coatings (like nickel, epoxy, or rubber) protect magnets from rust and physical wear, especially neodymium which can corrode easily.<\/li>\n<li>While the coating doesn\u2019t increase magnetic strength, it can help maintain performance over time by preventing damage.<\/li>\n<\/ul>\n<p><strong>3. Temperature Ratings<\/strong><\/p>\n<ul>\n<li>Every magnet has a maximum operating temperature. When it gets too hot, it can lose strength\u2014sometimes permanently.<\/li>\n<li>Higher grades don\u2019t always mean higher heat resistance. For example, standard N neodymium grades start losing power at around 80\u00b0C (176\u00b0F), but high-temp grades like N35SH can handle up to 150\u00b0C (302\u00b0F).<\/li>\n<\/ul>\n<p><strong>4. Environmental Conditions and Demagnetization Risks<\/strong><\/p>\n<ul>\n<li>Strong opposing magnetic fields, heat, or heavy mechanical stress can cause a magnet to lose some or all of its magnetism.<\/li>\n<li>For outdoor use or exposure to moisture, weatherproof coatings or corrosion-resistant materials like samarium cobalt are better choices.<\/li>\n<\/ul>\n<p>Keeping these factors in mind when selecting a magnet can save you from buying the wrong type for your project\u2014whether it\u2019s for industrial machinery, hobby builds, or custom fixtures.<\/p>\n<h2>Why Choose NBAEM Quality Magnetic Materials and Expert Guidance<\/h2>\n<p>When you\u2019re dealing with magnets, the right grade, pull force, and gauss rating make all the difference. <strong>NBAEM<\/strong> offers a full range of magnetic materials \u2013 from <strong>neodymium (N35\u2013N52)<\/strong> to ferrite, alnico, and samarium cobalt, in various shapes, sizes, and coatings to suit different applications.<\/p>\n<h3>Wide Product Range by Grade and Type<\/h3>\n<p>We stock magnets for light-duty consumer products all the way to heavy-duty <strong>industrial and engineering use<\/strong>.
