Compilation of suggested goods

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 about 10 years, their strength decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • By applying a shiny coating of nickel, gold, or silver, 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 shape) even at temperatures up to 230°C and above...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Key role in modern technologies – are used in HDD drives, electric drive mechanisms, medical equipment and other advanced devices.

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 metal holder. 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,
  • 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Possible danger to health from tiny fragments of magnets are risky, when accidentally ingested, which is particularly important in the context of children's health. It's also worth noting that small elements of these magnets have the potential to complicate diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

Neodymium magnetic are particularly delicate, resulting in shattering.

Magnets made of neodymium are delicate as well as will break 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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

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 alternatively in their path when they attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.

  Do not give neodymium magnets to youngest 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.

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

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.

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

The magnet is coated with nickel - be careful 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.

Keep neodymium magnets away from 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. 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.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Keep neodymium magnets as far away as possible from 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.
