Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Besides their stability, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after ten 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 reflective layer of gold, the element gains a modern look,
- They have exceptional magnetic induction on the surface of the magnet,
- With the right combination of materials, they reach increased thermal stability, enabling operation at or above 230°C (depending on the form),
- The ability for custom shaping as well as adaptation to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
- Key role in modern technologies – they are utilized in computer drives, electromechanical systems, medical equipment as well as sophisticated instruments,
- Thanks to their power density, small magnets offer high magnetic performance, in miniature format,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to external force, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage and increases its overall robustness,
- They lose field intensity at high temperatures. Most neodymium magnets experience permanent decline 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, especially when used outside, we recommend using encapsulated magnets, such as those made of polymer,
- Limited ability to create threads in the magnet – the use of a external casing is recommended,
- Health risk due to small fragments may arise, when consumed by mistake, which is crucial in the context of child safety. Furthermore, small elements from these assemblies may hinder health screening after being swallowed,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which may limit large-scale applications
Be Cautious with Neodymium Magnets
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
Neodymium magnets bounce and clash mutually within a radius of several to almost 10 cm from each other.
Neodymium magnets are highly susceptible to damage, resulting in breaking.
Neodymium magnetic are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. 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 demagnetize at high temperatures.
Although magnets are generally resilient, 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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are the strongest magnets ever invented. Their strength can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium magnets are not recommended for 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.
Maintain neodymium magnets away from youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. 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.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
