Neodymium (NdFeB) 20x20 mm Disc & Cylinder Magnet - High-Strength Rare Earth Magnet

The Neodymium (NdFeB) 20×20 mm Disc & Cylinder Magnet is a large, high‑strength rare‑earth magnet designed for applications demanding powerful magnetic force within a compact disc or cylindrical form factor. Manufactured from Neodymium‑Iron‑Boron (NdFeB) alloy, this magnet delivers excellent magnetic performance versus conventional ferrite magnets of similar size.

With a 20 mm diameter and 20 mm height, this magnet functions both as a disc and cylindrical rod, making it ideal for heavy‑duty magnetic fixtures, precision mechanical assemblies, electronic devices, industrial holding systems, and strong DIY applications. The magnet is commonly nickel‑plated (Ni‑Cu‑Ni) for enhanced corrosion resistance and surface durability.
