Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their stability, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (in laboratory conditions),
- They remain magnetized despite exposure to strong external fields,
- In other words, due to the shiny gold coating, the magnet obtains an stylish appearance,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- With the right combination of compounds, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
- Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which expands their application range,
- Key role in cutting-edge sectors – they serve a purpose in HDDs, electromechanical systems, medical equipment along with sophisticated instruments,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of magnetic elements:
- They may fracture when subjected to a sudden impact. If the magnets are exposed to external force, it is suggested to place them 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 strength,
- 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,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of rubber for outdoor use,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is not feasible,
- Health risk related to magnet particles may arise, if ingested accidentally, which is crucial in the protection of children. Furthermore, miniature parts from these magnets have the potential to complicate medical imaging once in the system,
- Due to expensive raw materials, their cost is above average,
Handle Neodymium Magnets Carefully
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.
Keep neodymium magnets away 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.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
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 alternatively a fracture.
The magnet coating contains nickel, so be cautious 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.
Neodymium magnets should not be around youngest children.
Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Keep neodymium magnets away from people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
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, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnetic are highly delicate, they easily fall apart and can crumble.
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. 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.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can shock you.
