Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose strength over time - after about 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit extremely 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 and the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
- Significant importance in the industry of new technologies – are used in computer drives, electric drive mechanisms, medical apparatus or other highly developed apparatuses.
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,
- They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape 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,
- 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 arising from small pieces of magnets can be dangerous, when accidentally ingested, which is crucial in the context of child safety. Additionally, miniscule components of these magnets can hinder the diagnostic process after entering the body.
Caution with Neodymium 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.
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. 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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets generate intense 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.
Magnets made of neodymium are highly fragile, they easily break as well as can become damaged.
Neodymium magnets 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 and coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise 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.
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Neodymium magnets can become demagnetized at high temperatures.
Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
