It is made from Neodymium‑Iron‑Boron (NdFeB) alloy, one of the strongest permanent magnet materials available, giving it significantly higher magnetic performance compared to conventional ferrite magnets of similar size. With an outer diameter of 10 mm, inner diameter of 3 mm, and 3 mm thickness, this ring magnet is ideal for precision mechanical assemblies, sensors, small motors, magnetic couplings, fixtures, and DIY applications. The magnet is typically nickel‑plated (Ni) to enhance corrosion resistance and surface durability, and is magnetized through the thickness (axial poles on the flat faces).\u003c\/p\u003e\n\u003ch4\u003eSpecifications:\u003c\/h4\u003e\n\u003ctable style=\"width: 100%;\"\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth style=\"text-align: center; width: 40.0185%;\"\u003eParameter\u003c\/th\u003e\n\u003cth style=\"text-align: center; width: 59.6415%;\"\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eMagnet Type\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eNeodymium (NdFeB) Rare Earth\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eShape\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eRing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eOuter Diameter (OD)\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003e10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eInner Diameter (ID)\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003e3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eThickness\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003e3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eGrade\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eN35 (or equivalent, unless specified)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eCoating\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eNickel (Ni‑Cu‑Ni)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eMagnetization Direction\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eAxial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eUp to ~80 °C (standard grade)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eMaterial Density\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003e~7.4–7.5 g\/cm³\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"text-align: center; width: 40.0185%;\"\u003eCorrosion Resistance\u003c\/td\u003e\n\u003ctd style=\"text-align: center; width: 59.6415%;\"\u003eModerate (plated surface)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4 data-start=\"1780\" data-end=\"1797\"\u003ePackage Includes:\u003c\/h4\u003e\n\u003cp data-start=\"1799\" data-end=\"1883\"\u003e1 x  Neodymium (NdFeB) 10x3x3 mm Ring Magnet - High-Strength Rare Earth Magnet\u003c\/p\u003e","brand":"MAG022","offers":[{"title":"Default Title","offer_id":45774026506474,"sku":"OTH-QC4399","price":19.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/6424\/6919\/files\/Neodymium_NdFeB_11x5x5mmRingMagnet-High-StrengthRareEarthMagnet.jpg?v=1767691361","url":"https:\/\/quartzcomponents.com\/products\/block-magnets-20mm-10mm","provider":"QuartzComponents","version":"1.0","type":"link"}
