Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They retain their magnetic properties for nearly ten years – the drop is just ~1% (in theory),
- They remain magnetized despite exposure to magnetic surroundings,
- In other words, due to the metallic silver coating, the magnet obtains an professional appearance,
- They exhibit elevated 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 form),
- Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which increases their usage potential,
- Key role in cutting-edge sectors – they serve a purpose in data storage devices, electromechanical systems, clinical machines or even high-tech tools,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in tiny dimensions, which allows for use in miniature devices
Disadvantages of NdFeB magnets:
- They can break when subjected to a heavy 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 reinforces its overall durability,
- High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent weakening 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 protective material for outdoor use,
- Limited ability to create internal holes in the magnet – the use of a housing is recommended,
- Health risk from tiny pieces may arise, when consumed by mistake, which is significant in the health of young users. Moreover, tiny components from these devices have the potential to disrupt scanning if inside the body,
- In cases of mass production, neodymium magnet cost is a challenge,
Be Cautious with Neodymium Magnets
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets may crack or alternatively crumble with careless connecting to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
Magnets are not toys, children should not play with them.
Remember that neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Magnets made of neodymium are highly fragile, they easily break as well as can become damaged.
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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can surprise you.
To use 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.
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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
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.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets can become demagnetized at high temperatures.
Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
