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 approximately 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field extremely well,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They exhibit very 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...
- Due to the option of accurate forming and 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 and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously 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 reduction in strength (although it is dependent on the form 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
- Health risk to health from tiny fragments of magnets pose a threat, if swallowed, which is crucial in the context of child safety. Furthermore, small elements of these devices can hinder the diagnostic process in case of swallowing.
Handle with Care: Neodymium Magnets
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage 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. Avoid placing neodymium magnets in close proximity to electronic devices.
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 alternatively crumble with uncontrolled joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them extremely firmly.
Neodymium magnets are not recommended for people with pacemakers.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Remember that neodymium magnets are not toys. Do not allow children to play 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 severe injuries, and even death.
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 are extremely fragile, resulting in shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can shock you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
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.
