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 have stable power, and over more than ten years their attraction force decreases symbolically – ~1% (according to theory),
- They remain magnetized despite exposure to magnetic surroundings,
- Because of the brilliant layer of gold, the component looks aesthetically refined,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- With the right combination of compounds, they reach significant thermal stability, enabling operation at or above 230°C (depending on the structure),
- Thanks to the flexibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in diverse shapes and sizes, which expands their functional possibilities,
- Important function in modern technologies – they serve a purpose in hard drives, electromechanical systems, healthcare devices and other advanced devices,
- Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of neodymium magnets:
- They may fracture when subjected to a strong impact. If the magnets are exposed to external force, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and additionally enhances its overall strength,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s structure). 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 advisable to use sealed magnets made of protective material for outdoor use,
- Limited ability to create precision features in the magnet – the use of a mechanical support is recommended,
- Possible threat linked to microscopic shards may arise, when consumed by mistake, which is crucial in the health of young users. It should also be noted that small elements from these magnets can complicate medical imaging if inside the body,
- Due to the price of neodymium, their cost is considerably higher,
Precautions
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 damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Dust and powder from neodymium magnets are highly 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.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
Magnets may crack or alternatively crumble with careless joining to each other. You can't approach them to each other. At a distance less than 10 cm you should hold them extremely strongly.
Do not bring neodymium magnets close to 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Keep neodymium magnets away from youngest children.
Remember that neodymium magnets are not toys. Do not allow children to play 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.
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.
Magnets made of neodymium are especially fragile, resulting in their breakage.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crumble. 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.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
