Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They do not lose their strength around 10 years – the decrease of strength is only ~1% (according to tests),
- They remain magnetized despite exposure to magnetic noise,
- By applying a bright layer of gold, the element gains a sleek look,
- They have very high magnetic induction on the surface of the magnet,
- With the right combination of materials, they reach increased 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 functional possibilities,
- Key role in advanced technical fields – they serve a purpose in computer drives, electromechanical systems, clinical machines as well as sophisticated instruments,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They may fracture when subjected to a strong impact. If the magnets are exposed to shocks, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall robustness,
- High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on height). 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 damp air can corrode. Therefore, for outdoor applications, we advise waterproof types made of rubber,
- Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
- Possible threat due to small fragments may arise, especially if swallowed, which is notable in the context of child safety. Additionally, small elements from these assemblies may interfere with diagnostics if inside the body,
- Due to expensive raw materials, their cost is considerably higher,
Exercise Caution with Neodymium Magnets
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 are known for being fragile, which can cause them to crumble.
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. 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 should not be near 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.
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.
Under no circumstances should neodymium magnets be brought close to 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.
Under no circumstances should neodymium magnets be placed 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
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. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
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.
Neodymium magnets bounce and also clash mutually within a radius of several to around 10 cm from each other.
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.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
