Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their immense strength, neodymium magnets offer the following advantages:
- Their power is durable, and after approximately ten years, it drops only by ~1% (theoretically),
- They show strong resistance to demagnetization from external field exposure,
- In other words, due to the shiny silver coating, the magnet obtains an professional appearance,
- They have extremely strong magnetic induction on the surface of the magnet,
- 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 shape),
- The ability for accurate shaping and adaptation to specific needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
- Important function in cutting-edge sectors – they are used in computer drives, rotating machines, medical equipment or even other advanced devices,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of rare earth magnets:
- They can break when subjected to a sudden impact. If the magnets are exposed to shocks, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture while also strengthens its overall robustness,
- High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on size). 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 humid environment – during outdoor use, we recommend using sealed magnets, such as those made of rubber,
- Limited ability to create internal holes in the magnet – the use of a mechanical support is recommended,
- Potential hazard related to magnet particles may arise, when consumed by mistake, which is notable in the context of child safety. It should also be noted that small elements from these assemblies have the potential to complicate medical imaging when ingested,
- Due to expensive raw materials, their cost is relatively high,
Notes with Neodymium Magnets
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.
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets can become demagnetized 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.
The magnet coating is made of nickel, so be cautious if you have an allergy.
Studies show a small percentage of people have allergies to certain metals, including 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
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 particularly delicate, resulting in damage.
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. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or in their path when attract. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.
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, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
