Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their strong holding force, neodymium magnets have these key benefits:
- They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (based on calculations),
- They show exceptional resistance to demagnetization from external field exposure,
- Because of the reflective layer of gold, the component looks visually appealing,
- Magnetic induction on the surface of these magnets is impressively powerful,
- Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- The ability for accurate shaping and adaptation to specific needs – neodymium magnets can be manufactured in multiple variants of geometries, which enhances their versatility in applications,
- Key role in advanced technical fields – they serve a purpose in data storage devices, electromechanical systems, diagnostic apparatus along with sophisticated instruments,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture and additionally reinforces its overall resistance,
- They lose power at increased temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to wet conditions can rust. Therefore, for outdoor applications, it's best to use waterproof types made of coated materials,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing threads directly in the magnet,
- Health risk from tiny pieces may arise, in case of ingestion, which is notable in the protection of children. Furthermore, small elements from these assemblies have the potential to disrupt scanning if inside the body,
- Due to expensive raw materials, their cost is relatively high,
Exercise Caution with Neodymium Magnets
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 can become demagnetized at high temperatures.
Despite the general resilience of magnets, 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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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 joining of neodymium magnets is not under control, then they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.
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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Keep neodymium magnets away from youngest children.
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.
Neodymium magnets are particularly delicate, resulting in damage.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.
