Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their tremendous strength, neodymium magnets offer the following advantages:
- Their power is maintained, and after approximately 10 years, it drops only by ~1% (theoretically),
- Their ability to resist magnetic interference from external fields is among the best,
- Thanks to the shiny finish and nickel coating, they have an visually attractive appearance,
- The outer field strength of the magnet shows remarkable magnetic properties,
- These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for custom shaping and customization to custom needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which enhances their versatility in applications,
- Wide application in advanced technical fields – they find application in HDDs, electromechanical systems, medical equipment and high-tech tools,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,
Disadvantages of NdFeB magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to external force, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage and reinforces its overall durability,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on form). 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 wet conditions can degrade. Therefore, for outdoor applications, we suggest waterproof types made of coated materials,
- Limited ability to create precision features in the magnet – the use of a housing is recommended,
- Health risk due to small fragments may arise, if ingested accidentally, which is important in the family environments. Furthermore, miniature parts from these magnets can interfere with diagnostics after being swallowed,
- Due to the price of neodymium, their cost is considerably higher,
Handle Neodymium Magnets with Caution
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.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Neodymium magnets are the strongest magnets ever invented. Their power 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.
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.
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 magnetic are extremely fragile, resulting in breaking.
Neodymium magnets are extremely delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from the wallet, computer, and TV.
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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
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.
Magnets attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.
The magnet is coated with nickel - be careful 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Be careful!
