Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- Their strength is maintained, and after around 10 years, it drops only by ~1% (according to research),
- Their ability to resist magnetic interference from external fields is notable,
- By applying a bright layer of silver, the element gains a clean look,
- The outer field strength of the magnet shows advanced magnetic properties,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- The ability for precise shaping and adaptation to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
- Key role in cutting-edge sectors – they are used in HDDs, electric drives, clinical machines along with sophisticated instruments,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,
Disadvantages of rare earth magnets:
- They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to physical collisions, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage and reinforces its overall robustness,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on size). 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 advisable to use sealed magnets made of plastic for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing fine shapes directly in the magnet,
- Safety concern related to magnet particles may arise, if ingested accidentally, which is significant in the health of young users. Moreover, minuscule fragments from these assemblies may complicate medical imaging when ingested,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Exercise Caution with Neodymium Magnets
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Neodymium magnets should not be near people with pacemakers.
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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Neodymium magnets are not toys. Do not allow children to play 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.
Magnets made of neodymium are extremely fragile, they easily fall apart as well as can crumble.
Neodymium magnets are fragile as well as 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Neodymium magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise you.
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.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
In the situation of placing a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.
If you have a nickel allergy, avoid contact with neodymium magnets.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.
Pay attention!
