Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time. After 10 years, their power decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • 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,
  • 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...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Significant importance in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical equipment or other modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • 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
  • Possible danger to health from tiny fragments of magnets pose a threat, if swallowed, which is crucial in the context of children's health. Additionally, tiny parts of these magnets can be problematic in medical diagnosis after entering the body.

Be Cautious with Neodymium Magnets

Dust and powder from neodymium magnets are 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.

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, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

The magnet coating contains nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

 Maintain neodymium magnets far from children.

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays 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.

Neodymium magnets can become demagnetized at high temperatures.

Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Neodymium magnetic are extremely fragile, resulting in their cracking.

Neodymium magnets are highly fragile, 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 collision between the magnets, small metal fragments can be dispersed in different directions.

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

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

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

Neodymium magnets are not recommended for people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

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