Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from their superior power, neodymium magnets have these key benefits:
- They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (according to literature),
- They are very resistant to demagnetization caused by external magnetic fields,
- In other words, due to the shiny silver coating, the magnet obtains an aesthetic appearance,
- They possess significant magnetic force measurable at the magnet’s surface,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- The ability for precise shaping and adaptation to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which enhances their versatility in applications,
- Wide application in advanced technical fields – they are utilized in computer drives, rotating machines, healthcare devices along with high-tech tools,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which makes them ideal in small systems
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally enhances its overall resistance,
- They lose strength at extreme temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of synthetic coating for outdoor use,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
- Health risk linked to microscopic shards may arise, especially if swallowed, which is crucial in the protection of children. Moreover, tiny components from these assemblies have the potential to hinder health screening after being swallowed,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Precautions
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
People with pacemakers are advised to avoid neodymium magnets.
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.
The magnet coating is made of nickel, so be cautious 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If joining of neodymium magnets is not under control, at that time they may crumble and crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other 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.
Do not give neodymium magnets to children.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Magnets made of neodymium are characterized by being fragile, which can cause them to crumble.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.
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.
Keep neodymium magnets away from TV, wallet, and computer HDD.
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 away from these electronic devices.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
