Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

  • They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
  • They have exceptionally high magnetic induction on the surface of the magnet,
  • Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
  • The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
  • Significant importance in the industry of new technologies – find application in computer drives, electric drive mechanisms, medical devices and very modern machines.

Disadvantages of neodymium magnets:

  • They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time 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 shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard to health from tiny fragments of magnets pose a threat, in case of ingestion, which becomes significant in the aspect of protecting young children. It's also worth noting that miniscule components of these magnets are able to complicate diagnosis after entering the body.

We Recommend Caution with Neodymium Magnets

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.

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

Studies show a small percentage of people have allergies to certain metals, including 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 can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Neodymium magnets jump and touch each other mutually within a radius of several to around 10 cm from each other.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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.

Never bring neodymium magnets close to a phone and GPS.

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

Neodymium magnetic are fragile as well as can easily crack as well as get 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.

Keep neodymium magnets away 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, 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 should not be around youngest children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

To raise awareness of why neodymium magnets are so dangerous, see the article titled How very dangerous are very strong neodymium magnets?.
