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 protect against demagnetization caused by external magnetic sources very well,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which amplifies their universality in usage.
- Wide application in the industry of new technologies – find application in hard drives, electric drive mechanisms, medical apparatus and other modern machines.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
- Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Possible danger to health from tiny fragments of magnets are risky, in case of ingestion, which becomes significant in the context of child safety. Additionally, miniscule components of these devices can complicate diagnosis after entering the body.
Handle Neodymium Magnets with Caution
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock 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.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Keep neodymium magnets away from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Keep neodymium magnets as far away as possible from GPS and smartphones.
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 can attract to each other, pinch the skin, and cause significant swellings.
If the joining of neodymium magnets is not controlled, then they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should hold them very strongly.
Neodymium magnetic are fragile as well as can easily crack as well as get damaged.
Neodymium magnets are characterized by considerable 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 connection between the magnets, sharp metal fragments can be dispersed in different directions.
Keep neodymium magnets away from TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
