Shopping tips

It is essential to select magnetic accessories from trusted manufacturers, which ensures high quality and safety when handling.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their tremendous field intensity, neodymium magnets offer the following advantages:

  • They do not lose their even during around 10 years – the reduction of power is only ~1% (according to tests),
  • Their ability to resist magnetic interference from external fields is impressive,
  • In other words, due to the glossy nickel coating, the magnet obtains an professional appearance,
  • They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
  • These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to build),
  • The ability for precise shaping or adjustment to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
  • Wide application in cutting-edge sectors – they are used in computer drives, rotating machines, clinical machines and other advanced devices,
  • Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of magnetic elements:

  • They are fragile when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall robustness,
  • Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, we advise waterproof types made of coated materials,
  • Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing complex structures directly in the magnet,
  • Potential hazard due to small fragments may arise, if ingested accidentally, which is important in the context of child safety. Moreover, small elements from these products can disrupt scanning once in the system,
  • High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Precautions

Neodymium magnets are not recommended for people with pacemakers.

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.

Neodymium magnets can become demagnetized at high temperatures.

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

 Keep neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.

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.

Dust and powder from neodymium magnets are highly 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 TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets can damage 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 are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If joining of neodymium magnets is not controlled, then they may crumble and also crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.

Keep neodymium magnets away from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are delicate as well as can easily break as well as shatter.

Neodymium magnets are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Safety precautions!

So you are aware of why neodymium magnets are so dangerous, read the article titled How very dangerous are very powerful neodymium magnets?.
