Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from their consistent holding force, neodymium magnets have these key benefits:
- They do not lose their even over around 10 years – the reduction of lifting capacity is only ~1% (theoretically),
- They show strong resistance to demagnetization from outside magnetic sources,
- In other words, due to the glossy nickel coating, the magnet obtains an aesthetic appearance,
- The outer field strength of the magnet shows elevated 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 magnetic form),
- With the option for customized forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
- Important function in new technology industries – they serve a purpose in data storage devices, electromechanical systems, diagnostic apparatus or even sophisticated instruments,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to physical collisions, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time increases its overall robustness,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent weakening 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,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of plastic for outdoor use,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is risky,
- Safety concern linked to microscopic shards may arise, in case of ingestion, which is crucial in the family environments. Furthermore, minuscule fragments from these devices might disrupt scanning when ingested,
- Due to a complex production process, their cost is considerably higher,
Caution with Neodymium Magnets
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or in their path when they attract. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that 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 away from these electronic devices.
Neodymium magnets can demagnetize at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
Magnets made of neodymium are highly delicate, they easily fall apart as well as can crumble.
Neodymium magnets are characterized by considerable 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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can 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.
The magnet is coated with nickel. Therefore, exercise caution 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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets are not toys, youngest 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.
Be careful!
