Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They have exceptionally high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate 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 various forms and dimensions, which enhances their versatility in applications.
- Significant importance in modern technologies – find application in hard drives, electric drive mechanisms, medical devices or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break 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 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 loss in strength (although it is worth noting that this is dependent on the shape 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 recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- 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 associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. Furthermore, miniscule components of these products can hinder the diagnostic process in case of swallowing.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets produce intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
In the case of placing a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
It is important to maintain neodymium magnets away from children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in 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.
Neodymium magnets are delicate and can easily crack as well as shatter.
Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will crack. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.
To use 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.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
