Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their magnetic performance, neodymium magnets are valued for these benefits:
- They have constant strength, and over more than 10 years their performance decreases symbolically – ~1% (in testing),
- They show strong resistance to demagnetization from external magnetic fields,
- By applying a shiny layer of silver, the element gains a clean look,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- With the option for tailored forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
- Important function in advanced technical fields – they find application in computer drives, electromechanical systems, medical equipment along with technologically developed systems,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them useful in miniature devices
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture and additionally strengthens its overall resistance,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of plastic for outdoor use,
- Limited ability to create complex details in the magnet – the use of a mechanical support is recommended,
- Possible threat related to magnet particles may arise, especially if swallowed, which is significant in the health of young users. Additionally, miniature parts from these magnets might complicate medical imaging if inside the body,
- In cases of large-volume purchasing, neodymium magnet cost is a challenge,
Caution with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
Even though magnets have been observed 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Neodymium magnetic are extremely fragile, they easily crack as well as can crumble.
Neodymium magnets are characterized by considerable fragility. 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If you have a finger between or on the path of attracting magnets, there may be a severe cut or even a fracture.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnets are the most powerful, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
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.
The strong magnetic field generated by neodymium magnets can destroy 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. Remember not to place neodymium magnets close to these electronic devices.
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 should not be in the vicinity children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
