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 approximately 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 nickel, gold, or silver finish, the element gains an visually attractive 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...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in modern technologies – are used in hard drives, electric motors, medical apparatus and other advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard to health from tiny fragments of magnets pose a threat, in case of ingestion, which becomes significant in the context of child safety. It's also worth noting that small elements of these products have the potential to be problematic in medical diagnosis when they are in the body.
Handle with Care: Neodymium Magnets
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or even a fracture may occur.
The magnet coating contains nickel, so be cautious if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets produce strong magnetic fields that can damage 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.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise 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.
Neodymium magnets should not be in the vicinity children.
Not all neodymium magnets are toys, so do not let children play with them. 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.
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.
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. 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.
Magnets made of neodymium are extremely fragile, resulting in breaking.
Magnets made of neodymium are fragile as well as will crack 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. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
