This guide is for makers, designers, engineers, and hobbyists seeking strong, compact magnetic solutions. The N35 Neodymium Magnet offers exceptional holding power in a small form factor, ideal for detailed projects. A key caveat is that these powerful magnets require careful handling to avoid pinching fingers or damaging sensitive electronics.

'N35' refers to the grade of the neodymium magnet, indicating its magnetic strength. N35 is a common and strong grade suitable for most applications.
Each magnet can support up to 2kg vertically when in perfect, flush contact with a thick, mild steel surface. This 'pull force' can be less in real-world applications depending on surface conditions and shear forces.
The magnets themselves are not inherently waterproof, but the triple nickel-copper-nickel coating provides good resistance to corrosion and moisture. However, prolonged submersion or exposure to harsh chemicals is not recommended.
It is not recommended to place these strong magnets close to electronic devices like computers, hard drives, smartphones, or credit cards, as they can potentially damage or erase data.
Store them in a cool, dry place. It's best to keep them separated by a non-magnetic material (like plastic or cardboard) or to allow them to stick to a steel plate to prevent them from attracting to each other and causing damage or injury.
While N35 grade magnets have good resistance to demagnetization, prolonged exposure to temperatures above 80°C (176°F) can begin to weaken their magnetic strength.
Neodymium magnets are very hard and brittle. Attempting to drill or machine them without specialized tools and techniques is likely to result in breakage. It is generally not feasible for most users.
Ensure the surface is clean, flat, and made of mild steel. The pull force is measured in ideal conditions (flush contact, thick steel); actual performance may vary. Check if another magnet is interfering or if the steel object is too thin.
Neodymium magnets are brittle. Avoid dropping them or allowing them to snap forcefully against metal or other magnets. If chipped, the magnetic strength may be slightly reduced, but it can often still be used if the damage is minor.
This is normal due to their strength. Slide them apart carefully, or use a tool to gently separate them to avoid pinching fingers. Store them with separation or in a way that prevents direct attraction.
Setup: These magnets are ready to use out of the package. No specific setup is required beyond placing them in their intended application. Ensure the surfaces they will attach to are clean, flat, and made of a suitable ferromagnetic material like mild steel for maximum pull strength.
Compatibility: They are compatible with any ferrous metal surface. When integrating into projects, consider the magnetic field's reach and potential interference with sensitive electronic components. They are not affected by water, but prolonged exposure to harsh chemicals may degrade the coating over time.
Care: Handle with care to avoid chipping or breaking. Keep magnets at least 12 inches away from magnetically sensitive devices such as pacemakers, credit cards, computers, and older CRT monitors. Store them with a steel plate or in a separate container to prevent them from attracting to each other and potentially causing damage or pinching fingers. Clean with a soft, dry or slightly damp cloth; avoid abrasive materials.
