FAQs

What does N42 grade mean?

N42 refers to the grade of the neodymium magnet, indicating its maximum energy product. Higher numbers generally mean a stronger magnet for its size. N42 is a high-performance grade offering excellent strength.

How should I store these magnets?

Store magnets in a cool, dry place, separated by non-magnetic material (like cardboard or plastic) or in a specialized magnetic storage container. Avoid storing them in direct contact with each other to prevent them from snapping together forcefully and potentially causing damage.

Are these magnets safe for children?

Due to their strong magnetic force and potential to chip, these magnets are not recommended for use by young children. Small magnets can pose a choking hazard and powerful magnetic fields can be dangerous if swallowed.

Can I use these magnets outdoors?

While the triple coating offers corrosion resistance, prolonged exposure to harsh weather conditions (heavy rain, salt air) may eventually lead to degradation of the coating and magnet. It is best to keep them dry and protected for maximum longevity.

What happens if I put two magnets together the wrong way?

If you attempt to force two magnets together with the same poles facing each other, they will repel. If they snap together, they will align with opposite poles facing each other. Be careful during this process as the force can be significant.

Can these magnets be drilled or modified?

Neodymium magnets are very hard and brittle. Attempting to drill or machine them without specialized equipment and techniques is likely to cause them to shatter. It is not recommended to modify these magnets.

Troubleshooting

Magnet not holding strongly enough

Ensure the magnet is directly attracting to a suitable ferrous material. Check for any intervening non-ferrous materials or coatings that may be weakening the magnetic field. Verify that the surface is clean.

Magnet arrived chipped or cracked

Neodymium magnets are inherently brittle. Inspect the packaging for damage. Contact the supplier with details of the damage for potential replacement options. Handle remaining magnets with extra care.

Difficulty separating magnets

Slide magnets apart rather than pulling directly. Use a non-magnetic tool or lever to assist in separation if necessary. Store with separators to prevent them from sticking tightly together.

Coating appears dull or corroded

Ensure the magnet is kept dry. If minor corrosion is present, gently clean with a soft cloth. Significant corrosion may indicate damage or prolonged exposure to moisture; contact the supplier if this is unexpected.

Pros and Cons

Pros

  • Extremely strong for their small size.
  • Corrosion-resistant due to triple coating.
  • Precise dimensions suitable for intricate projects.
  • Versatile for both creative and technical applications.
  • Smooth, clean finish enhances aesthetics.

Cons

  • Can be brittle and prone to chipping or cracking if mishandled.
  • Powerful magnetic force can cause pinching injuries if fingers are caught.
  • Requires careful separation when stored in bulk.
  • Not suitable for high-temperature applications.
  • Potential for damage if dropped or impacted.

Setup, Compatibility & Care

Setup:

These magnets are ready for immediate use. Simply position them according to your design requirements. Be mindful of their strong magnetic pull when handling and placing them, especially near sensitive electronic devices or ferrous materials.

Compatibility:

  • Ferrous Materials: Magnets will strongly attract to iron, nickel, cobalt, and their alloys (e.g., steel). Ensure compatibility with surrounding materials.
  • Electronics: Keep magnets at a safe distance from hard drives, credit cards, magnetic strips, CRT monitors, and other sensitive electronics to prevent data loss or damage.
  • Temperature: Avoid exposing these magnets to temperatures above 80°C (176°F) as this can permanently demagnetize them.

Care:

  • Handling: Handle with care to avoid chipping or cracking. Use plastic or cardboard separators between magnets when storing or moving.
  • Cleaning: Clean with a soft, dry or slightly damp cloth. Avoid abrasive cleaners or solvents that could damage the coating.
  • Storage: Store in a cool, dry place, away from direct sunlight and heat sources. Keep separated or in a container that mitigates their magnetic force to prevent accidental sticking.
