Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their exceptional pulling force, neodymium magnets offer the following advantages:
- They virtually do not lose power, because even after ten years, the performance loss is only ~1% (based on calculations),
- They are very resistant to demagnetization caused by external field interference,
- The use of a polished nickel surface provides a refined finish,
- The outer field strength of the magnet shows elevated magnetic properties,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
- The ability for accurate shaping as well as customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
- Key role in modern technologies – they are used in hard drives, rotating machines, clinical machines along with sophisticated instruments,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to external force, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally increases its overall strength,
- High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on shape). 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,
- They rust in a wet environment – during outdoor use, we recommend using waterproof magnets, such as those made of polymer,
- Limited ability to create threads in the magnet – the use of a magnetic holder is recommended,
- Safety concern due to small fragments may arise, in case of ingestion, which is important in the protection of children. It should also be noted that miniature parts from these devices may complicate medical imaging if inside the body,
- Due to the price of neodymium, their cost is relatively high,
Exercise Caution with Neodymium Magnets
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
In the case of holding a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.
Neodymium magnets are the strongest magnets ever invented. Their power 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.
Do not place neodymium magnets 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 damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are extremely fragile, they easily fall apart as well as can crumble.
Neodymium magnets are characterized by significant fragility. 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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Keep neodymium magnets away from 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.
Neodymium magnets can demagnetize at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Magnets are not toys, youngest should not play with them.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
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.
