Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- Their magnetic field is maintained, and after around 10 years, it drops only by ~1% (theoretically),
- They protect against demagnetization induced by ambient magnetic influence very well,
- By applying a reflective layer of silver, the element gains a modern look,
- 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),
- The ability for accurate shaping and customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
- Wide application in advanced technical fields – they are used in HDDs, rotating machines, clinical machines and high-tech tools,
- Thanks to their power density, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They may fracture when subjected to a strong impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time strengthens its overall durability,
- They lose strength at extreme temperatures. Most neodymium magnets experience permanent degradation 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,
- They rust in a wet environment. If exposed to rain, we recommend using moisture-resistant magnets, such as those made of rubber,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is not feasible,
- Health risk linked to microscopic shards may arise, especially if swallowed, which is notable in the context of child safety. It should also be noted that miniature parts from these devices can interfere with diagnostics when ingested,
- In cases of mass production, neodymium magnet cost is a challenge,
Notes with Neodymium Magnets
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength 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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
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.
Dust and powder from neodymium magnets are highly 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.
Under no circumstances should neodymium magnets be placed 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. Avoid placing neodymium magnets in close proximity to electronic devices.
Neodymium magnets are characterized by being fragile, which can cause them to shatter.
Magnets made of neodymium are extremely delicate, and by joining them in an uncontrolled manner, they will crack. 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.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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 a fracture.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Be careful!
