Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They have stable power, and over nearly 10 years their attraction force decreases symbolically – ~1% (according to theory),
- Their ability to resist magnetic interference from external fields is notable,
- Because of the lustrous layer of nickel, the component looks aesthetically refined,
- They have exceptional magnetic induction on the surface of the magnet,
- With the right combination of compounds, they reach significant thermal stability, enabling operation at or above 230°C (depending on the form),
- The ability for precise shaping as well as customization to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Significant impact in modern technologies – they serve a purpose in data storage devices, electric drives, diagnostic apparatus as well as technologically developed systems,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They may fracture when subjected to a sudden impact. If the magnets are exposed to external force, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture and additionally enhances its overall strength,
- They lose power at high temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a moist environment, especially when used outside, we recommend using sealed magnets, such as those made of non-metallic materials,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing complex structures directly in the magnet,
- Health risk linked to microscopic shards may arise, when consumed by mistake, which is crucial in the family environments. Furthermore, tiny components from these assemblies can interfere with diagnostics after being swallowed,
- In cases of tight budgets, neodymium magnet cost may be a barrier,
Caution with Neodymium Magnets
Keep neodymium magnets away from TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can damage 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 away from these electronic devices.
Magnets made of neodymium are fragile and can easily break and get damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
The magnet is coated with nickel. Therefore, exercise caution 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.
Never bring neodymium magnets close to a phone and GPS.
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 can attract to each other, pinch the skin, and cause significant injuries.
In the case of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to 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.
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.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Neodymium magnets should not be near 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.
Exercise caution!
