Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
- They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (in laboratory conditions),
- They are highly resistant to demagnetization caused by external magnetic sources,
- By applying a bright layer of silver, the element gains a modern look,
- They have extremely strong magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
- The ability for precise shaping and adjustment to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
- Significant impact in advanced technical fields – they serve a purpose in HDDs, electromechanical systems, clinical machines and other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a sudden impact. If the magnets are exposed to mechanical hits, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and additionally increases its overall durability,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (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 damp environment. For outdoor use, we recommend using sealed magnets, such as those made of polymer,
- Limited ability to create complex details in the magnet – the use of a magnetic holder is recommended,
- Potential hazard from tiny pieces may arise, in case of ingestion, which is crucial in the family environments. It should also be noted that small elements from these products have the potential to complicate medical imaging if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Handle with Care: Neodymium Magnets
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Neodymium magnets will bounce and also touch together within a radius of several to almost 10 cm from each other.
Neodymium magnets should not be around children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Keep neodymium magnets away from GPS and smartphones.
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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets are especially delicate, which leads to shattering.
Neodymium magnets are fragile and will crack 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. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Magnetic 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
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.
Be careful!
