Neodymium (NdFeB) 6x3x6 mm Ring Magnet - High-Strength Rare Earth Magnet

The Neodymium (NdFeB) 6×3×6 mm Ring Magnet is a compact, high‑strength rare‑earth magnet designed for applications that require powerful magnetic force in a small ring (donut) form factor. Manufactured from Neodymium‑Iron‑Boron (NdFeB) alloy, this magnet provides significantly higher magnetic performance than conventional ferrite magnets of similar dimensions. With an outer diameter of 6 mm, inner diameter of 3 mm, and 6 mm thickness, it’s ideal for use in precision mechanical assemblies, motors, sensors, magnetic couplings, fixtures, educational projects, and small DIY applications. The magnet is typically nickel‑plated (Ni‑Cu‑Ni) to enhance corrosion resistance and surface durability, and is axially magnetized (through thickness), which is common for NdFeB ring magnets below 80 °C.Specifications:ParameterSpecificationMagnet TypeNeodymium (NdFeB) Rare EarthShapeRingOuter Diameter (OD)6 mmInner Diameter (ID)3 mmThickness6 mmGradeN35 (or equivalent, unless specified)CoatingNickel (Ni‑Cu‑Ni)Magnetization DirectionAxialOperating TemperatureUp to ~80 °C (standard grade)Material Density~7.4–7.6 g/cm³Corrosion ResistanceModerate (plated surface) Package Includes:1 x 6×3×6 mm Neodymium (NdFeB) Ring Magnet – High‑Strength Rare Earth Magnet
