Shopping tips

As an example, magnetic strips are applied to organize spaces, e.g., in cooking areas to hold tools, or in offices to pin reminders.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their superior magnetic energy, neodymium magnets have these key benefits:

  • They do not lose their even during approximately 10 years – the loss of strength is only ~1% (based on measurements),
  • They show superior resistance to demagnetization from outside magnetic sources,
  • In other words, due to the metallic silver coating, the magnet obtains an professional appearance,
  • They have extremely strong magnetic induction on the surface of the magnet,
  • Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
  • Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in diverse shapes and sizes, which expands their functional possibilities,
  • Wide application in modern technologies – they are used in data storage devices, electromechanical systems, clinical machines along with high-tech tools,
  • Thanks to their power density, small magnets offer high magnetic performance, in miniature format,

Disadvantages of NdFeB magnets:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to external force, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage and reinforces its overall strength,
  • High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent loss 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,
  • Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, it's best to use waterproof types made of rubber,
  • The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
  • Possible threat due to small fragments may arise, if ingested accidentally, which is notable in the family environments. Moreover, miniature parts from these devices have the potential to complicate medical imaging if inside the body,
  • High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Caution with Neodymium Magnets

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

If you have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or even a fracture.

  Magnets are not toys, youngest should not play with them.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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

Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnetic are especially delicate, resulting in shattering.

Neodymium magnetic are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

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

Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

If you have a nickel allergy, avoid contact with neodymium magnets.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Caution!

So you are aware of why neodymium magnets are so dangerous, read the article titled How dangerous are powerful neodymium magnets?.
