Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

  • They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (according to literature),
  • They remain magnetized despite exposure to strong external fields,
  • Thanks to the shiny finish and gold coating, they have an visually attractive appearance,
  • They possess intense magnetic force measurable at the magnet’s surface,
  • Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
  • Thanks to the possibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in different geometries, which expands their functional possibilities,
  • Key role in cutting-edge sectors – they are used in computer drives, electric drives, clinical machines or even other advanced devices,
  • Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a powerful impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time increases its overall strength,
  • High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
  • They rust in a damp environment. If exposed to rain, we recommend using sealed magnets, such as those made of plastic,
  • The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is risky,
  • Safety concern related to magnet particles may arise, in case of ingestion, which is important in the family environments. Moreover, miniature parts from these magnets have the potential to interfere with diagnostics once in the system,
  • In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Safety Precautions

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are the strongest magnets ever created, and their power can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Avoid contact with neodymium magnets if you have a nickel allergy.

Studies clearly indicate a small percentage of people who suffer from metal allergies such as nickel. An allergic reaction often manifests as skin redness and rash. If you have a nickel allergy, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

 Maintain neodymium magnets away from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Neodymium magnets are especially fragile, resulting in shattering.

Magnets made of neodymium are extremely delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
