Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
- Key role in modern technologies – are used in HDD drives, electric motors, medical apparatus and very advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Possible danger associated with microscopic parts of magnets can be dangerous, if swallowed, which is crucial in the context of child safety. It's also worth noting that small elements of these magnets have the potential to complicate diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from people with pacemakers.
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.
Avoid contact with neodymium magnets if you have a nickel 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.
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.
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 will crack or alternatively crumble with careless joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them very firmly.
Neodymium magnetic are extremely fragile, they easily crack and can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets should not be around children.
Remember that 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 are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
