Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose strength over time - after 10 years, their strength decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic sources extremely well,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They have 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...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Wide application in the industry of new technologies – find application in HDD drives, electric motors, medical apparatus and other advanced devices.
Disadvantages of neodymium magnets:
- They are fragile 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,
- Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- 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
- Potential hazard arising from small pieces of magnets can be dangerous, if swallowed, which becomes significant in the context of child safety. Furthermore, small elements of these products have the potential to hinder the diagnostic process after entering the body.
Caution with Neodymium Magnets
Neodymium magnets can become demagnetized 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise 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.
Do not give neodymium magnets to youngest children.
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.
Keep neodymium magnets away from GPS and smartphones.
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 attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets will bounce and also clash together within a radius of several to almost 10 cm from each other.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets are highly susceptible to damage, resulting in breaking.
Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
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, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
