Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their exceptional magnetic power, neodymium magnets offer the following advantages:
- Their magnetic field remains stable, and after around ten years, it drops only by ~1% (theoretically),
- Their ability to resist magnetic interference from external fields is among the best,
- The use of a polished nickel surface provides a eye-catching finish,
- The outer field strength of the magnet shows remarkable magnetic properties,
- Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
- The ability for accurate shaping or adaptation to specific needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
- Wide application in advanced technical fields – they find application in HDDs, electric motors, diagnostic apparatus or even sophisticated instruments,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to shocks, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time increases its overall resistance,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). 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,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of protective material for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing threads directly in the magnet,
- Potential hazard linked to microscopic shards may arise, when consumed by mistake, which is important in the health of young users. Moreover, small elements from these assemblies might interfere with diagnostics if inside the body,
- In cases of large-volume purchasing, neodymium magnet cost may be a barrier,
Handle Neodymium Magnets Carefully
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.
Neodymium magnets are known for their fragility, which can cause them to shatter.
Neodymium magnets are characterized by considerable fragility. Neodymium magnetic 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.
Magnets are not toys, youngest should not play with them.
Neodymium magnets are not toys. Be cautious and make sure no child plays 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 severe injuries, and even death.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
Make sure not to bring neodymium magnets close to the 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 destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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.
Neodymium magnets can demagnetize 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.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Neodymium magnets will jump and clash together within a radius of several to almost 10 cm from each other.
Neodymium magnets are the strongest magnets ever created, and their strength can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
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.
Pay attention!
So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
