Our 20x11x3mm block magnets deliver optimal strength and size, offering impressive pull force without bulk. Crafted from premium N52 Grade Neodymium, they guarantee maximum magnetic performance and long-term reliability. Their versatile rectangular shape is perfect for flush mounting, embedding, and creating secure, discreet closures.

Each magnet features enhanced durability with a robust Nickel-Copper-Nickel (Ni-Cu-Ni) triple coating, providing superior protection against corrosion and a professional finish. We ensure consistent quality, manufacturing under strict controls for uniform strength and dependable performance across every piece.

These magnets are incredibly versatile. In industrial & manufacturing, they excel in jigs, fixtures, and robust machinery closures. For heavy-duty closures, they securely fasten cabinet doors, toolboxes, and bespoke furniture. They’re ideal for craft & DIY projects, creating powerful hidden latches or securely mounting items. In retail & exhibitions, use them for secure, reusable mounting of displays. They’re also useful for educational & prototyping in physics experiments and functional prototypes requiring strong magnetic fields.

At MagSmith, we commit to providing only the highest quality magnets, meticulously sourced and rigorously tested for your toughest projects. Choose us for superior magnetic performance and lasting durability. Order your 20x11x3mm neodymium block magnets today!
