Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their immense strength, neodymium magnets offer the following advantages:
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They show strong resistance to demagnetization from external magnetic fields,
- In other words, due to the shiny nickel coating, the magnet obtains an professional appearance,
- They possess intense magnetic force measurable at the magnet’s surface,
- With the right combination of compounds, they reach increased thermal stability, enabling operation at or above 230°C (depending on the design),
- With the option for fine forming and targeted design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
- Key role in new technology industries – they serve a purpose in data storage devices, electric drives, clinical machines or even technologically developed systems,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks while also reinforces its overall strength,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a moist environment. For outdoor use, we recommend using waterproof 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 holes directly in the magnet,
- Possible threat linked to microscopic shards may arise, when consumed by mistake, which is significant in the context of child safety. Furthermore, miniature parts from these magnets may hinder health screening once in the system,
- In cases of tight budgets, neodymium magnet cost may be a barrier,
Handle Neodymium Magnets with Caution
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If you have a finger between or on the path of attracting magnets, there may be a large cut or a fracture.
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
It is essential to maintain neodymium magnets away from children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets are not recommended for 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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
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 are among the strongest magnets on Earth. The astonishing force they generate between each other 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.
The magnet is coated with nickel - be careful if you have an 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Magnets made of neodymium are extremely fragile, leading to shattering.
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. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Magnetic 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Caution!
