Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

  • They do not lose their strength (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic sources,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
  • They exhibit very high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Wide application in the industry of new technologies – are used in hard drives, electric drive mechanisms, medical equipment and other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Potential hazard associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which is crucial in the aspect of protecting young children. Furthermore, small elements of these products are able to complicate diagnosis in case of swallowing.

Handle with Care: Neodymium Magnets

 It is important to keep neodymium magnets away from youngest children.

Remember that 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 significant injuries, and even death.

Magnets made of neodymium are extremely delicate, they easily break as well as can become damaged.

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. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Avoid bringing neodymium magnets close to a phone or GPS.

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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

In the situation of placing a finger in the path of a neodymium magnet, in such a case, a cut or even a fracture may occur.

The magnet coating is made of nickel, so be cautious if you have an 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.

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

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

Neodymium magnets can become demagnetized at high temperatures.

Whilst Neodymium magnets can demagnetize 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.

Neodymium magnets should not be near 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.

Keep neodymium magnets away from the wallet, computer, and TV.

Strong 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
