The energy product of these magnets is eight times greater than that of anisotropic ferrite magnets, and they possess excellent mechanical strength. Since they oxidize easily, they are usually nickel-plated. The disadvantages of these magnets lie in their heat sensitivity and the careful handling they require.\u003c\/span\u003e\u003ch2 style=\"text-align: center;\"\u003e\u003c\/h2\u003e\u003cem\u003e\u003cstrong\u003eNeodymium magnets are available in 4 different diameter sizes: 10 mm, 15 mm, 18 mm, and 21 mm, all with a thickness of 2 mm.\u003c\/strong\u003e\u003c\/em\u003e\u003cp style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/www.panafargo.com\/wp-content\/uploads\/2022\/02\/Imanes-De-Neodimio-En-Forma-De-Moneda-Tamanos-Diferentes.jpg\"\u003e\u003cimg class=\"alignnone size-medium wp-image-33407\" src=\"https:\/\/www.panafargo.com\/wp-content\/uploads\/2022\/02\/Imanes-De-Neodimio-En-Forma-De-Moneda-Tamanos-Diferentes-300x300.jpg\" alt=\"imanes-de-neodimio\" width=\"300\" height=\"300\"\u003e\u003c\/a\u003e\u003c\/p\u003e\u003ch2 style=\"text-align: center;\"\u003e\u003cem\u003e\u003cstrong\u003eWhy are Neodymium Magnets so widely used? \u003c\/strong\u003e\u003c\/em\u003e\u003c\/h2\u003e\u003cspan data-contrast=\"auto\"\u003eNeodymium magnets are not just simple refrigerator magnets.
