DIYMAG Large Neodymium Magnet, 1.57"x0.79"(40x20mm) 125LBS Strong Magnets Round High Power Rare Earth Magnets Permanent Magnetic Disc 1 Piece

Premium Grade Neodymium Disc Magnets – 40mm x 20mm, Nickel-Plated, for Heavy-Duty Holding, DIY &amp; Industrial Use <br> Unmatched Strength &amp; Durability <br> Engineered with a core of premium Neodymium-Iron-Boron (NdFeB), the world’s strongest permanent magnet material, these discs deliver exceptional holding power. The polished nickel plating provides a corrosion-resistant, shiny silver finish that looks professional and lasts. Axially magnetized for focused pull strength and rated for continuous use up to 176 ° F (80 ° C), they are built for reliability in the most demanding conditions. <br> Designed for Substantial Projects – Large 40mm x 20mm Size <br> With a substantial diameter of 40mm (1.57") and a thickness of 20mm (0.79"), these magnets offer a powerful magnetic face and significant volume for heavy-duty applications. Manufactured to precise tolerances (±0.2mm), they ensure consistent performance and a secure, strong hold that far exceeds ordinary ceramic or flexible magnets. <br> Extremely Versatile – From the Workshop to Your Home <br> Their incredible strength makes them the ideal solution for a vast range of tasks: <br> Workshop &amp; Garage: ​ Secure tools, hold jigs, retrieve metal parts, or organize equipment. <br> Industrial &amp; Commercial: ​ Use in prototyping, machinery, as magnetic holders, or in sensory applications. <br> Home &amp; Kitchen: ​ Create powerful magnetic knife strips, spice racks, or secure items to appliances. <br> DIY &amp; Crafts: ​ Perfect for advanced projects, building prototypes, models, or custom closures that require serious strength. <br> Science &amp; Education: ​ Excellent for demonstrations, experiments, and STEM projects involving magnetic fields. <br> Important Handling &amp; Safety Instructions <br> Neodymium magnets are powerful and require careful handling to ensure safety and longevity. <br> FRAGILE: ​ They are sintered (powder-based) and can chip, crack, or shatter if allowed to slam together. Always handle them with care and keep them separated. <br> SAFE SEPARATION: ​ To separate two magnets, slide ​ one sideways off the other—do not pull them directly apart, as this can cause injury or damage. <br> MAXIMIZING HOLD: ​ For the strongest pull force, use on a smooth, flat, ferrous (iron or steel) surface. The grip strength is reduced on uneven or non-ferrous materials. <br> WARNING: ​ Keep away from children, pacemakers, credit cards, electronics, and mechanical watches. The powerful force can cause serious pinch injuries.
