Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their long-term stability, neodymium magnets provide the following advantages:
- They do not lose their power around 10 years – the loss of strength is only ~1% (according to tests),
- They show exceptional resistance to demagnetization from external field exposure,
- The use of a decorative nickel surface provides a eye-catching finish,
- The outer field strength of the magnet shows advanced magnetic properties,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to build),
- The ability for accurate shaping as well as adjustment to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
- Significant impact in new technology industries – they are used in data storage devices, electric motors, healthcare devices or even high-tech tools,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They are fragile when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and additionally increases its overall robustness,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- They rust in a humid environment. If exposed to rain, we recommend using waterproof magnets, such as those made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing holes directly in the magnet,
- Potential hazard from tiny pieces may arise, if ingested accidentally, which is crucial in the protection of children. Additionally, tiny components from these assemblies can complicate medical imaging once in the system,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Caution with Neodymium Magnets
Magnets made of neodymium are extremely fragile, they easily break and can crumble.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crack. 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 collision between the magnets, sharp metal fragments can be dispersed in different directions.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets generate strong magnetic fields that can damage 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. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If the joining of neodymium magnets is not under control, then they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should have them very firmly.
Neodymium magnets are the most powerful magnets ever created, and 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 disruption to the magnets.
Neodymium magnets should not be near 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
The magnet is coated with nickel. Therefore, exercise caution if you have an 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.
Keep neodymium magnets away from youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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.
Pay attention!
