Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, 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 nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Key role in the industry of new technologies – are used in computer drives, electric drive mechanisms, medical apparatus 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 metal holder. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
- High temperatures can reduce the power 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,
- 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Health risk to health from tiny fragments of magnets pose a threat, when accidentally ingested, which is crucial in the context of child safety. Additionally, miniscule components of these devices have the potential to hinder the diagnostic process in case of swallowing.
Notes with Neodymium Magnets
Dust and powder from neodymium magnets are 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 noted for being fragile, which can cause them to become damaged.
Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium 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.
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. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets as far away as possible from GPS and smartphones.
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.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or in their path when attract. Magnets, depending on their size, can even cut off a finger or there can be a serious pressure or a fracture.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnets are the strongest magnets ever invented. Their power 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.
