Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They have unchanged lifting capacity, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
  • They remain magnetized despite exposure to magnetic surroundings,
  • Because of the brilliant layer of gold, the component looks aesthetically refined,
  • Magnetic induction on the surface of these magnets is very strong,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
  • Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which broadens their functional possibilities,
  • Wide application in new technology industries – they are used in HDDs, electromechanical systems, medical equipment or even sophisticated instruments,
  • Relatively small size with high magnetic force – neodymium magnets offer strong power in compact dimensions, which makes them ideal in small systems

Disadvantages of magnetic elements:

  • They are fragile when subjected to a powerful impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time strengthens its overall resistance,
  • High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). 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,
  • Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of rubber for outdoor use,
  • Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing holes directly in the magnet,
  • Potential hazard linked to microscopic shards may arise, if ingested accidentally, which is important in the protection of children. Furthermore, small elements from these assemblies can interfere with diagnostics after being swallowed,
  • Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Be Cautious with Neodymium Magnets

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 among the strongest magnets on Earth. The surprising force they generate between each other can shock you.

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

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.

 It is important to maintain neodymium magnets out of reach from children.

Neodymium magnets are not toys. Do not allow children to play 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.

Neodymium magnets can demagnetize at high temperatures.

Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If the joining of neodymium magnets is not controlled, at that time they may crumble and crack. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets are highly susceptible to damage, leading to breaking.

Neodymium magnets are characterized by considerable fragility. 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 collision between the magnets, sharp metal fragments can be dispersed in different directions.

Warning!
