Durable Nickel-Cpper-Nickel 3-layer Coated magnet. 🧲 1.25" OD x 0.5" ID x 0.25" Neodymium Ring Magnet — High Strength Rare Earth Permanent Magnet for Industrial, Engineering, and DIY Applications Unmatched Strength in a Compact Ring Design Experience precision, power, and performance in one magnetic masterpiece. This 1.25-inch outer diameter, 0.5-inch inner diameter, 0.25-inch thick ring magnet is forged from advanced Neodymium–Iron–Boron (NdFeB) material — one of the strongest magnetic compounds ever developed. Its compact ring shape concentrates energy efficiently, allowing powerful attraction and repulsion forces in a small, lightweight form factor. Whether you’re an engineer, craftsman, or innovator, this magnet is built to perform where strength and precision matter most. Engineered for Maximum Magnetic Performance Each ring magnet is produced under strict quality control standards to deliver consistent magnetic performance and durability. The magnetization is axial — through the thickness — ensuring a balanced and uniform magnetic field across both flat faces. This provides superior stability for coupling, levitation, or rotational systems. The precise dimensions (1.25" OD × 0.5" ID × 0.25" thick) are carefully machined to tight tolerances, ensuring perfect symmetry and a smooth surface finish. This makes it easy to integrate into assemblies or prototypes where even a millimeter of misalignment could affect performance. When mounted on steel surfaces or paired with compatible materials, this magnet demonstrates a powerful grip and energy density, delivering impressive holding power relative to its size. Triple Coated for Durability and Corrosion Resistance To protect the raw magnetic core, every ring magnet receives a triple-layer plating of Nickel–Copper–Nickel (Ni–Cu–Ni). This finish provides a corrosion-resistant barrier that enhances longevity, prevents rust, and maintains consistent performance even in environments with moderate humidity or temperature fluctuations. The outer layer offers a subtle, metallic sheen — clean and professional — while also helping reduce surface wear during installation or handling. This protective coating also makes the magnet suitable for long-term use in various projects where exposure to air, oil, or moisture may occur, such as manufacturing lines, lab experiments, or workshop applications. Compact Power — Built for Industrial and Creative Use Despite its small size, this magnet’s field strength can generate a substantial pulling force when placed on thick steel surfaces. Its combination of small dimensions and concentrated energy makes it a staple in hundreds of professional and educational settings. Common Applications: ⚙️ Engineering & Prototyping: Used in sensors, couplings, and magnetic torque transfer systems. 🧪 Science Experiments & Education: Perfect for demonstrating repulsion, attraction, and rotational dynamics. 🧰 Home & Workshop Projects: Ideal for tool organization, mounting, and small mechanical fixtures. 🚗 Automotive & Mechanical Systems: Assists in closures, detection systems, and positioning mechanisms. 🎨 Art & Design Projects: Creates interactive, floating, or kinetic sculptures with magnetic balance. 🧼 Household Organization: Perfect for magnetic racks, holders, or custom fixtures that need clean, strong connections. Wherever you need controlled magnetic power in a precise circular form — this ring magnet delivers. How It Works — The Magnetic Field Advantage Ring magnets produce a concentrated magnetic flux that radiates from the flat faces and edges, creating a dynamic field pattern. This geometry allows rotational devices to spin smoothly or align accurately in magnetic arrays. When paired with another magnet of the same size but opposite polarity, they exhibit both repulsive and attractive interactions depending on orientation — a perfect way to visualize energy flow and polarity in physics or mechanical designs. Their circular symmetry makes them ideal for reducing drag or creating levitating effects in demonstration setups.
