Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
- Key role in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical equipment or very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Health risk to health from tiny fragments of magnets can be dangerous, if swallowed, which is crucial in the aspect of protecting young children. Furthermore, small elements of these magnets can complicate diagnosis when they are in the body.
Caution with Neodymium Magnets
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), 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.
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.
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. You should especially avoid placing neodymium magnets near electronic devices.
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. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Avoid contact with neodymium magnets 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.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets jump and clash mutually within a radius of several to around 10 cm from each other.
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can demagnetize 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 are noted for being fragile, which can cause them to crumble.
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 pieces can be propelled in various directions at high speed. Eye protection is recommended.
