Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
  • They possess very high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
  • The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
  • Wide application in advanced technologically fields – are utilized in hard drives, electric motors, medical apparatus and very advanced devices.

Disadvantages of neodymium magnets:

  • They are fragile 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,
  • 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 shape 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
  • Potential hazard arising from small pieces of magnets can be dangerous, when accidentally ingested, which is particularly important in the aspect of protecting young children. Furthermore, small elements of these products are able to complicate diagnosis after entering the body.

Exercise 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

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.

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

Neodymium magnets produce 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. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to put fingers between magnets or in their path when they attract. Magnets, depending on their size, can even cut off a finger or alternatively there can be a significant pressure or a fracture.

Neodymium magnets are the strongest magnets ever invented. Their strength can surprise you.

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

Do not bring neodymium magnets close to GPS and smartphones.

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.

Neodymium magnetic are highly delicate, they easily fall apart as well as can crumble.

Neodymium magnets are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

The magnet is coated with nickel - be careful 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 can lose their magnetism when subjected to high temperatures.

  Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.

Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
