Neodymium (NdFeB) 10x3x3 mm Ring Magnet - High-Strength Rare Earth Magnet

The Neodymium (NdFeB) 10×3×3 mm Ring Magnet is a compact, high‑strength rare‑earth magnet designed for applications that require strong magnetic force in a ring (donut) form factor. 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).Specifications:ParameterSpecificationMagnet TypeNeodymium (NdFeB) Rare EarthShapeRingOuter Diameter (OD)10 mmInner Diameter (ID)3 mmThickness3 mmGradeN35 (or equivalent, unless specified)CoatingNickel (Ni‑Cu‑Ni)Magnetization DirectionAxialOperating TemperatureUp to ~80 °C (standard grade)Material Density~7.4–7.5 g/cm³Corrosion ResistanceModerate (plated surface) Package Includes:1 x Neodymium (NdFeB) 10x3x3 mm Ring Magnet - High-Strength Rare Earth Magnet
