Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from their strong power, neodymium magnets have these key benefits:
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (according to theory),
- Their ability to resist magnetic interference from external fields is notable,
- By applying a reflective layer of gold, the element gains a sleek look,
- They have exceptional magnetic induction on the surface of the magnet,
- Thanks to their exceptional temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
- Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which expands their functional possibilities,
- Key role in new technology industries – they are used in hard drives, rotating machines, healthcare devices as well as other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time enhances its overall robustness,
- They lose strength at extreme temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to damp air can rust. Therefore, for outdoor applications, we advise waterproof types made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing holes directly in the magnet,
- Possible threat linked to microscopic shards may arise, if ingested accidentally, which is crucial in the family environments. Additionally, miniature parts from these magnets have the potential to hinder health screening if inside the body,
- Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications
Be Cautious with Neodymium Magnets
It is important to keep neodymium magnets out of reach from youngest children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
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.
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.
Neodymium magnets will bounce and contact together within a distance of several to around 10 cm from each other.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and 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.
Magnets made of neodymium are extremely fragile, resulting in their cracking.
Neodymium magnets are fragile and will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets produce strong magnetic fields that can interfere 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 the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
