Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their immense magnetic power, neodymium magnets offer the following advantages:
- Their magnetic field is maintained, and after approximately 10 years, it drops only by ~1% (theoretically),
- They are very resistant to demagnetization caused by external magnetic fields,
- By applying a reflective layer of nickel, the element gains a sleek look,
- Magnetic induction on the surface of these magnets is impressively powerful,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- With the option for fine forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving design adaptation,
- Wide application in modern technologies – they are utilized in data storage devices, electric drives, clinical machines and high-tech tools,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in small dimensions, which makes them useful in small systems
Disadvantages of NdFeB magnets:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to shocks, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and additionally strengthens its overall strength,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (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 humid environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of polymer,
- Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing threads directly in the magnet,
- Possible threat due to small fragments may arise, if ingested accidentally, which is crucial in the family environments. Additionally, tiny components from these devices have the potential to complicate medical imaging if inside the body,
- In cases of tight budgets, neodymium magnet cost is a challenge,
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Avoid bringing neodymium magnets close to a phone or 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 are highly delicate, they easily fall apart as well as can crumble.
Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power 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.
Keep neodymium magnets away from the wallet, computer, and TV.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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 can become demagnetized at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
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 can attract to each other, pinch the skin, and cause significant swellings.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or in their path when they attract. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.
