POWERFUL - Applied Magnets Rare Earth Neodymium Magnets have an estimated pull force of 84 lbs. and are triple layer coated (nickel-copper-nickel) for maximum durability and protection against corrosion. This rectangular block magnet measures 4" x 1/2" x 1/2" and is finished with a nickel-copper-nickel coating for lasting durability. Designed for professional, educational, and household use, it delivers reliable performance across a wide range of projects. With its elongated shape and slim profile, this magnet is easy to integrate into assemblies, closures, and organizational systems. Built for Durability Each magnet is precision cut and coated in a protective triple-layer finish. The nickel-copper-nickel plating enhances corrosion resistance, improves wear protection, and provides a smooth, polished surface. This construction ensures that the magnet maintains consistent performance even with repeated use. Wide Range of Applications This 4-inch block magnet is versatile and can be used in: 🛠️ Workshops & Garages – Organize tools, secure fasteners, or mount fixtures. 📌 Office & Storage – Attach signage, displays, or filing accessories to metal surfaces. 🧪 Education & Demonstrations – Ideal for classroom experiments, physics lessons, or hands-on demonstrations. 🏠 DIY Projects – Hidden cabinet closures, furniture builds, or creative design applications. 🏭 Industrial Settings – Suitable for alignment, mounting, and lightweight holding solutions. Its slim but long design provides effective surface contact while remaining compact enough to use in custom assemblies. Handling & Safety Magnets of this type should always be handled with care: Pinch Hazard: Can attract to metal surfaces or other magnets suddenly; handle one at a time. Not for Children: These are not toys and should never be ingested. Electronics Safety: Keep away from computers, cards, and other sensitive devices. Brittle Material: Magnets can chip or crack if they collide or are dropped. Medical Precautions: Avoid use near pacemakers or other medical implants. Heat Sensitivity: Performance may be reduced if exposed to sustained heat above 175°F (80°C). By following these guidelines, the magnet will remain safe and reliable for long-term use.
