Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their exceptional pulling force, neodymium magnets offer the following advantages:
- They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- Their ability to resist magnetic interference from external fields is impressive,
- By applying a shiny layer of nickel, the element gains a modern look,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to build),
- The ability for custom shaping and adaptation to custom needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which enhances their versatility in applications,
- Wide application in cutting-edge sectors – they are used in computer drives, rotating machines, diagnostic apparatus or even technologically developed systems,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to shocks, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally increases its overall robustness,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (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 wise to use sealed magnets made of rubber for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing threads directly in the magnet,
- Potential hazard related to magnet particles may arise, if ingested accidentally, which is significant in the protection of children. Additionally, miniature parts from these magnets might interfere with diagnostics after being swallowed,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Precautions
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
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 especially delicate, which leads to shattering.
Neodymium magnetic are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from 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.
Under no circumstances should neodymium magnets be brought close to 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.
Keep neodymium magnets away from TV, wallet, and computer HDD.
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. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a significant injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.
It is essential to keep neodymium magnets away from children.
Remember that 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.
Exercise caution!
