Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their remarkable field intensity, neodymium magnets offer the following advantages:
- Their magnetic field is durable, and after approximately ten years, it drops only by ~1% (according to research),
- Their ability to resist magnetic interference from external fields is among the best,
- Because of the lustrous layer of silver, the component looks aesthetically refined,
- They have extremely strong magnetic induction on the surface of the magnet,
- With the right combination of magnetic alloys, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the structure),
- The ability for accurate shaping as well as adaptation to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
- Significant impact in advanced technical fields – they are utilized in HDDs, electric drives, diagnostic apparatus as well as sophisticated instruments,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,
Disadvantages of NdFeB magnets:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time increases its overall resistance,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s structure). 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 synthetic coating for outdoor use,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is not feasible,
- Possible threat linked to microscopic shards may arise, especially if swallowed, which is notable in the health of young users. Additionally, miniature parts from these products can interfere with diagnostics if inside the body,
- In cases of tight budgets, neodymium magnet cost may be a barrier,
Safety Precautions
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets should not be around youngest children.
Neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnetic are particularly fragile, resulting in damage.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
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 around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a serious injury may occur. Depending on how huge the neodymium magnets are, they can lead to a cut or alternatively a fracture.
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 the strongest magnets ever created, and 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.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Make sure not to bring neodymium magnets close to the 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.
