N42 Neodymium Magnets - 10mm X 5mm X 2mm Thick - 1.1Kg Pull

'N42' refers to the grade of the Neodymium magnet. The 'N' stands for Neodymium, and '42' is a number indicating the maximum energy product, which correlates to its strength. N42 is a high-performance grade, offering significant magnetic force relative to its size.

The 1.1kg pull force is measured by pulling the magnet directly away from a thick, flat steel plate under ideal conditions. The actual holding force in a real-world application may vary depending on the thickness and type of steel, any intervening materials, and the angle of pull.

The triple nickel-copper-nickel coating provides good resistance to corrosion, making them suitable for many environmental conditions. However, prolonged exposure to harsh conditions or saltwater is not recommended and may eventually lead to corrosion. For submersed applications, consider additional protective measures.

Due to their strong magnetic force and small size, these magnets are NOT suitable for children. If swallowed, multiple magnets can attract to each other through the intestinal walls, causing severe injury and requiring emergency medical attention.

When two Neodymium magnets snap together with force, they can chip, crack, or shatter due to the sudden impact. It's important to handle them carefully, allowing them to attract gently or using a sliding motion to separate them.

Yes, these magnets can be glued using strong adhesives suitable for magnets and your project material. Common choices include super glue (cyanoacrylate) or epoxy. Ensure the surface of the magnet and the item it's being attached to are clean and dry for best adhesion.

Store magnets separately, with a barrier like cardboard or plastic between them, to prevent them from attracting to each other. Keep them in a cool, dry place away from direct heat and electronic devices. Never store them directly against each other without separation.

Ensure the metal surface is made of a ferrous material (like steel). Check if the magnet is in direct, flush contact with the surface. Clean both the magnet and the surface to remove any debris or coatings that might be interfering.

Verify the magnets are N42 grade and the stated pull force is for ideal conditions (flush contact with thick mild steel). Ensure magnets are not stored too close together or exposed to extreme heat, which can reduce magnetism over time. Check for any damage to the coating or the magnet itself.

Handle magnets with extreme care. Avoid letting them snap together forcefully, especially with other magnets or large metal objects. Ensure they are stored with a separator to prevent strong attraction. Use them in applications where impact is minimized.

Slide one magnet off the other rather than pulling directly apart. If they are strongly stuck, try to get a thin, non-metallic object (like a plastic card) between them to help break the seal.
