Advantages and disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They do not lose their even over around ten years – the reduction of strength is only ~1% (theoretically),
- Their ability to resist magnetic interference from external fields is notable,
- Thanks to the shiny finish and gold coating, they have an visually attractive appearance,
- Magnetic induction on the surface of these magnets is very strong,
- With the right combination of materials, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
- With the option for tailored forming and precise design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
- Wide application in modern technologies – they are used in HDDs, electric motors, medical equipment or even technologically developed systems,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally enhances its overall resistance,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing complex structures directly in the magnet,
- Possible threat linked to microscopic shards may arise, when consumed by mistake, which is notable in the context of child safety. It should also be noted that minuscule fragments from these products might complicate medical imaging once in the system,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Exercise Caution with Neodymium Magnets
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.
Keep neodymium magnets away from 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. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets are the most powerful magnets ever created, and their strength can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium magnetic are delicate as well as 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.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Maintain neodymium magnets away from youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If you have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or even a fracture.
