Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their consistent holding force, neodymium magnets have these key benefits:
- They have constant strength, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
- They are highly resistant to demagnetization caused by external magnetic fields,
- In other words, due to the shiny gold coating, the magnet obtains an professional appearance,
- They exhibit superior levels of magnetic induction near the outer area of the magnet,
- With the right combination of magnetic alloys, they reach significant thermal stability, enabling operation at or above 230°C (depending on the design),
- The ability for custom shaping as well as customization to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
- Key role in new technology industries – they are utilized in computer drives, electric drives, diagnostic apparatus as well as other advanced devices,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of neodymium magnets:
- They may fracture when subjected to a strong impact. If the magnets are exposed to physical collisions, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and additionally increases its overall robustness,
- They lose strength at high temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a damp environment. If exposed to rain, we recommend using sealed magnets, such as those made of non-metallic materials,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing fine shapes directly in the magnet,
- Safety concern from tiny pieces may arise, when consumed by mistake, which is significant in the protection of children. Moreover, miniature parts from these devices might hinder health screening when ingested,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Handle Neodymium Magnets with Caution
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium 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 the joining of neodymium magnets is not controlled, then they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Keep neodymium magnets away from TV, wallet, and computer HDD.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock 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 disruption to the magnets.
Magnets made of neodymium are highly delicate, they easily break and can crumble.
Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable 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.
Neodymium magnets should not be around children.
Neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
