Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They exhibit very 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 form) even at temperatures of 230°C or higher...
- 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 motors, medical equipment and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and at the same time 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,
- 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,
- 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 can be dangerous, if swallowed, which is particularly important in the context of children's health. Furthermore, tiny parts of these products are able to hinder the diagnostic process after entering the body.
Precautions with Neodymium Magnets
Neodymium magnetic are delicate as well as can easily break and get damaged.
Magnets made of neodymium are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Neodymium magnets generate 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 destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
People with pacemakers are advised to avoid neodymium magnets.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets will crack or crumble with uncontrolled joining to each other. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
Magnets should not be treated as toys. Therefore, it is not recommended for 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets can demagnetize at high temperatures.
Whilst 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.
