Shopping tips

However, it is essential to handle them with caution, as strong magnets may be fragile or damage tech equipment, such as phones or data carriers. Additionally, small accessories like NeoCube balls may pose a risk to young kids due to the possibility of swallowing.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their immense magnetic power, neodymium magnets offer the following advantages:

  • They have stable power, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
  • They show exceptional resistance to demagnetization from external field exposure,
  • The use of a polished nickel surface provides a refined finish,
  • The outer field strength of the magnet shows remarkable magnetic properties,
  • With the right combination of magnetic alloys, they reach significant thermal stability, enabling operation at or above 230°C (depending on the form),
  • Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which broadens their application range,
  • Significant impact in new technology industries – they are utilized in computer drives, rotating machines, clinical machines as well as other advanced devices,
  • Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of neodymium magnets:

  • They can break when subjected to a strong impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage while also reinforces its overall robustness,
  • Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
  • They rust in a wet environment, especially when used outside, we recommend using waterproof magnets, such as those made of plastic,
  • Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing threads directly in the magnet,
  • Safety concern due to small fragments may arise, especially if swallowed, which is crucial in the family environments. It should also be noted that miniature parts from these devices can hinder health screening after being swallowed,
  • High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications

Be Cautious with Neodymium Magnets

Neodymium magnets should not be near people with pacemakers.

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 primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or in their path when they attract. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a serious pressure or a fracture.

  Do not give neodymium magnets to children.

Neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

The magnet coating contains nickel, so be cautious if you have a nickel 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.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets can demagnetize at high temperatures.

Despite the fact that 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.

Magnets made of neodymium are characterized by being fragile, which can cause them to shatter.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.

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.

Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Safety precautions!

So that know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous very powerful neodymium magnets.
