Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (based on calculations),
- They show superior resistance to demagnetization from external field exposure,
- Thanks to the shiny finish and silver coating, they have an visually attractive 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 shape),
- With the option for fine forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
- Wide application in new technology industries – they are used in HDDs, electric motors, healthcare devices and sophisticated instruments,
- Compactness – despite their small size, they deliver powerful magnetism, 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 external force, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture and increases its overall robustness,
- They lose power at elevated temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to humidity can oxidize. Therefore, for outdoor applications, we recommend waterproof types made of plastic,
- Limited ability to create threads in the magnet – the use of a housing is recommended,
- Health risk due to small fragments may arise, if ingested accidentally, which is important in the context of child safety. Moreover, small elements from these products may interfere with diagnostics after being swallowed,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Precautions
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Magnets may crack or alternatively crumble with uncontrolled joining to each other. You can't move them to each other. At a distance less than 10 cm you should have them very strongly.
Neodymium magnets should not be near 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.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Neodymium magnets are the strongest magnets ever created, and their power can shock you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Neodymium magnets produce intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Never bring neodymium magnets close to a phone and GPS.
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.
The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnetic are particularly delicate, which leads to shattering.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will break. Magnets made of neodymium 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.
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.
Magnets are not toys, youngest should not play with them.
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.
Exercise caution!
