Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, 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 highly resistant to demagnetization by external magnetic sources,
- In other words, thanks to the glossy nickel, gold, or silver finish, 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 a wide range of shapes and sizes, which amplifies their universality in usage.
- Significant importance in advanced technologically fields – are utilized in HDD drives, electric drive mechanisms, medical equipment and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. 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 shape 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,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard associated with microscopic parts of magnets pose a threat, in case of ingestion, which is particularly important in the context of children's health. Additionally, tiny parts of these magnets are able to complicate diagnosis after entering the body.
Be Cautious with Neodymium Magnets
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets may crack or crumble with careless connecting to each other. You can't approach them to each other. At a distance less than 10 cm you should hold them very strongly.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Neodymium magnets should not be around 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.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy 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.
Magnets made of neodymium are particularly delicate, which leads to their breakage.
Magnets made of neodymium are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Keep neodymium magnets away from 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.
The magnet is coated with nickel - be careful 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
