Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They do not lose their even during nearly ten years – the decrease of power is only ~1% (based on measurements),
- They show superior resistance to demagnetization from outside magnetic sources,
- By applying a shiny layer of gold, the element gains a modern look,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which increases their functional possibilities,
- Important function in cutting-edge sectors – they are utilized in HDDs, rotating machines, clinical machines or even technologically developed systems,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,
Disadvantages of neodymium magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to shocks, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage and additionally reinforces its overall robustness,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of synthetic coating 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,
- Health risk related to magnet particles may arise, if ingested accidentally, which is significant in the protection of children. Additionally, miniature parts from these assemblies might hinder health screening when ingested,
- High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Handle with Care: Neodymium Magnets
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Magnets made of neodymium are extremely delicate, they easily crack as well as can crumble.
Neodymium magnets are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets can become demagnetized 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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Magnets are not toys, children should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
The magnet is coated with nickel. Therefore, exercise caution if you have an allergy.
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.
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.
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.
In the situation of holding a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.
Be careful!
