Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (in laboratory conditions),
- Their ability to resist magnetic interference from external fields is impressive,
- In other words, due to the shiny gold coating, the magnet obtains an aesthetic appearance,
- Magnetic induction on the surface of these magnets is impressively powerful,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- With the option for customized forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
- Significant impact in modern technologies – they are used in hard drives, rotating machines, clinical machines as well as other advanced devices,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to external force, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time enhances its overall durability,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Magnets exposed to moisture can degrade. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing holes directly in the magnet,
- Possible threat from tiny pieces may arise, when consumed by mistake, which is important in the health of young users. Moreover, tiny components from these devices have the potential to interfere with diagnostics if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Exercise Caution with Neodymium Magnets
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Do not give neodymium magnets to children.
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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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.
Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can shock you at first.
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.
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 can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
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.
In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or even a fracture may occur.
Magnets made of neodymium are known for their fragility, which can cause them to become damaged.
Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
