Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They do not lose their even during nearly ten years – the decrease of lifting capacity is only ~1% (theoretically),
- They remain magnetized despite exposure to magnetic surroundings,
- The use of a polished nickel surface provides a smooth finish,
- They possess strong magnetic force measurable at the magnet’s surface,
- With the right combination of compounds, they reach increased thermal stability, enabling operation at or above 230°C (depending on the form),
- The ability for precise shaping or customization to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
- Key role in cutting-edge sectors – they are utilized in computer drives, electric motors, diagnostic apparatus and other advanced devices,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They can break when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage and additionally enhances its overall durability,
- High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Magnets exposed to moisture can rust. Therefore, for outdoor applications, we suggest waterproof types made of coated materials,
- Limited ability to create internal holes in the magnet – the use of a housing is recommended,
- Potential hazard from tiny pieces may arise, if ingested accidentally, which is crucial in the family environments. Furthermore, small elements from these devices might complicate medical imaging if inside the body,
- Due to a complex production process, their cost is relatively high,
Exercise Caution with Neodymium Magnets
Avoid contact with neodymium magnets if you have a nickel 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
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 magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets are highly susceptible to damage, resulting in breaking.
Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Magnets are not toys, youngest should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS 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 can attract to each other, pinch the skin, and cause significant injuries.
Neodymium magnets will jump and clash together within a distance of several to almost 10 cm from each other.
Warning!
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
