Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their remarkable pulling force, neodymium magnets offer the following advantages:
- They virtually do not lose power, because even after 10 years, the decline in efficiency is only ~1% (according to literature),
- They remain magnetized despite exposure to strong external fields,
- By applying a shiny layer of gold, the element gains a sleek look,
- Magnetic induction on the surface of these magnets is very strong,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- With the option for fine forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
- Wide application in new technology industries – they find application in computer drives, electric drives, healthcare devices along with other advanced devices,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of NdFeB magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall durability,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a humid environment. If exposed to rain, we recommend using moisture-resistant magnets, such as those made of polymer,
- Limited ability to create precision features in the magnet – the use of a housing is recommended,
- Safety concern from tiny pieces may arise, if ingested accidentally, which is notable in the protection of children. It should also be noted that miniature parts from these assemblies can complicate medical imaging if inside the body,
- In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,
Precautions
Avoid contact with neodymium magnets if you have a nickel allergy.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
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.
Neodymium magnets are the most powerful magnets ever created, and their power can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
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 attract to each other, pinch the skin, and cause significant injuries.
If you have a finger between or alternatively on the path of attracting magnets, there may be a large cut or even a fracture.
Neodymium magnetic are highly susceptible to damage, resulting in shattering.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. 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.
Neodymium magnets can become demagnetized at high temperatures.
Even though magnets have been found 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.
Magnets are not toys, youngest should not play with them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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. You should especially avoid placing neodymium magnets near electronic devices.
