Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They do not lose their power nearly 10 years – the decrease of strength is only ~1% (based on measurements),
- They show strong resistance to demagnetization from external field exposure,
- By applying a reflective layer of gold, the element gains a clean look,
- Magnetic induction on the surface of these magnets is notably high,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in different geometries, which increases their application range,
- Significant impact in cutting-edge sectors – they serve a purpose in HDDs, rotating machines, diagnostic apparatus or even sophisticated instruments,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to external force, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time enhances its overall strength,
- 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 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 wise to use sealed magnets made of synthetic coating for outdoor use,
- The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is not feasible,
- Safety concern due to small fragments may arise, in case of ingestion, which is important in the family environments. It should also be noted that miniature parts from these assemblies can hinder health screening after being swallowed,
- Due to the price of neodymium, their cost is relatively high,
Exercise Caution with Neodymium Magnets
Neodymium magnetic are highly fragile, they easily crack and can become damaged.
Neodymium magnetic are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Neodymium magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
The magnet is coated with nickel - be careful 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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If have a finger between or on the path of attracting magnets, there may be a serious cut or even a fracture.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
The strong magnetic field generated by neodymium magnets 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.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their strength can shock you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
Avoid bringing neodymium magnets close to a phone or GPS.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are not recommended for 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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Remember that neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
