Neodymium (NdFeB) 11x5x5 mm Ring Magnet - High-Strength Rare Earth Magnet

The Neodymium (NdFeB) 11×5×5 mm Ring Magnet is a compact, high‑strength rare‑earth magnet designed for applications that require strong magnetic force in a small ring (donut) form factor. Manufactured from Neodymium‑Iron‑Boron (NdFeB) alloy, this magnet delivers significantly higher magnetic performance than conventional ferrite magnets of similar size. With an outer diameter of 11 mm, inner diameter of 5 mm, and 5 mm thickness, it is ideal for precision mechanical assemblies, motors, sensors, magnetic couplings, fixtures, and hobby or DIY projects. The magnet is typically nickel‑plated (Ni‑Cu‑Ni) to enhance corrosion resistance and surface durability, and is axially magnetized (magnetization through the thickness).
