Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field extremely well,
- 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,
- Magnetic neodymium magnets are characterized by very 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 or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Key role in advanced technologically fields – find application in HDD 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, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose power 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest 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
- Possible danger arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of children's health. Furthermore, miniscule components of these magnets are able to complicate diagnosis in case of swallowing.
Caution with Neodymium Magnets
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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 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 can demagnetize at high temperatures.
While Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
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 significant injuries, and even death.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets jump and also touch each other mutually within a distance of several to around 10 cm from each other.
Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Avoid contact with neodymium magnets 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.
Neodymium magnets are extremely fragile, they easily break as well as can crumble.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnetic 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, small metal fragments can be dispersed in different directions.
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are very powerful neodymium magnets?.
