Shopping tips

Still, it is important to use them carefully, as strong magnets may be fragile or damage electronic devices, such as phones or data carriers. Additionally, small accessories like NeoCube balls may pose a hazard to young kids due to the possibility of swallowing.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

  • They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
  • They protect against demagnetization induced by external magnetic influence very well,
  • In other words, due to the metallic nickel coating, the magnet obtains an professional appearance,
  • They exhibit superior levels of magnetic induction near the outer area of the magnet,
  • Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
  • The ability for accurate shaping as well as customization to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
  • Significant impact in cutting-edge sectors – they serve a purpose in computer drives, electromechanical systems, diagnostic apparatus or even high-tech tools,
  • Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which makes them useful in small systems

Disadvantages of magnetic elements:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture while also strengthens its overall durability,
  • Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Due to corrosion risk in humid conditions, it is common to use sealed magnets made of rubber for outdoor use,
  • The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is difficult,
  • Safety concern from tiny pieces may arise, especially if swallowed, which is crucial in the protection of children. Additionally, minuscule fragments from these products have the potential to hinder health screening after being swallowed,
  • In cases of tight budgets, neodymium magnet cost is a challenge,

Handle with Care: Neodymium Magnets

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.

Keep neodymium magnets away from 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.

Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

Keep neodymium magnets away from GPS and smartphones.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

  Neodymium magnets should not be around 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.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnetic are extremely fragile, resulting in breaking.

Neodymium magnets are characterized by significant fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.

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

Magnetic 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

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 attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.

Exercise caution!
