This guide is for hobbyists, crafters, engineers, and manufacturers seeking high-strength, compact magnetic solutions. The key benefit is the exceptional magnetic force delivered by these neodymium magnets in a small form factor, ideal for demanding applications. A potential caveat is their strong pull force, requiring careful handling to avoid pinching. This product is a pack of 10 N35 grade neodymium magnets, each measuring 8mm in diameter and 4mm in thickness, featuring a protective triple coating for corrosion resistance and a smooth finish. They are known for their resistance to demagnetization and have poles on opposite faces.

'N35' refers to the grade of the neodymium magnet, indicating its magnetic strength. N indicates Neodymium, and 35 is a numerical value representing the maximum energy product, with higher numbers indicating stronger magnets.
Due to their brittleness, drilling or machining these magnets is not recommended and can easily cause them to break. They are designed to be used as-is or embedded in other materials.
No, these magnets are not suitable for children. Their strong magnetic force can cause them to pinch skin severely or be a choking hazard if swallowed. If swallowed, they can cause serious internal injury.
Store magnets at least 1-2 inches apart or with a non-magnetic material like cardboard or plastic between them to prevent them from attracting each other. Keep them away from electronic devices and magnetic media.
The triple coating (nickel, copper, nickel) is designed for durability and corrosion resistance. Under normal use and care, it should last a long time. Avoid abrasive cleaning or harsh environments that could damage the coating.
The maximum recommended operating temperature for N35 grade neodymium magnets is typically around 80°C (176°F). Exceeding this temperature can permanently weaken their magnetic strength.
Ensure the object being attracted is made of a ferrous material. Clean both the magnet and the surface of the object. Verify the distance is within the effective range of the magnet.
These magnets are brittle. Handle with care, sliding them apart rather than yanking. If chipped, inspect for sharp edges and use with caution, especially around children or in sensitive applications. A minor chip may not significantly impact holding power.
Slide the magnets apart using a sideways motion rather than pulling directly. If they are stuck to a ferrous surface, use a lever to gently pry them away from the surface before attempting to separate them from each other.
Setup: These magnets are ready to use straight from the pack. Due to their strong pull, it is recommended to slide them apart rather than pulling directly when separating them, especially when they are stuck to metal surfaces or other magnets. Ensure the surfaces they are attaching to are clean and free of debris for optimal holding strength.
Compatibility: These magnets are compatible with most ferrous metals (iron, nickel, cobalt) and other magnets. They can be used in conjunction with non-ferrous materials by embedding them or attaching them to such materials using adhesives. Note that their magnetic field can interfere with sensitive electronic devices and magnetic storage media.
Care: To maintain their performance and appearance:
