Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from their notable power, neodymium magnets have these key benefits:
- They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (according to literature),
- They are extremely resistant to demagnetization caused by external field interference,
- In other words, due to the glossy gold coating, the magnet obtains an aesthetic appearance,
- The outer field strength of the magnet shows advanced magnetic properties,
- Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
- Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in diverse shapes and sizes, which broadens their functional possibilities,
- Important function in modern technologies – they are utilized in data storage devices, rotating machines, medical equipment as well as other advanced devices,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them useful in miniature devices
Disadvantages of rare earth magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to physical collisions, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time reinforces its overall robustness,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). 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,
- Magnets exposed to damp air can corrode. Therefore, for outdoor applications, we advise waterproof types made of plastic,
- Limited ability to create precision features in the magnet – the use of a mechanical support is recommended,
- Safety concern related to magnet particles may arise, if ingested accidentally, which is important in the family environments. Moreover, minuscule fragments from these magnets might complicate medical imaging after being swallowed,
- Due to the price of neodymium, their cost is relatively high,
Precautions
The magnet coating is made of nickel, so be cautious if you have an 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.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
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.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnetic are highly susceptible to damage, resulting in their cracking.
Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If joining of neodymium magnets is not controlled, then they may crumble and crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
