Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their immense field intensity, neodymium magnets offer the following advantages:
- They do not lose their magnetism, even after approximately 10 years – the decrease of power is only ~1% (according to tests),
- They show strong resistance to demagnetization from external magnetic fields,
- The use of a decorative gold surface provides a smooth finish,
- They have extremely strong magnetic induction on the surface of the magnet,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for custom shaping or customization to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which amplifies their functionality across industries,
- Significant impact in cutting-edge sectors – they find application in computer drives, electric drives, clinical machines as well as high-tech tools,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of magnetic elements:
- 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 protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and additionally increases its overall durability,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a wet environment – during outdoor use, we recommend using encapsulated magnets, such as those made of non-metallic materials,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is difficult,
- Health risk from tiny pieces may arise, in case of ingestion, which is important in the protection of children. Moreover, tiny components from these devices can hinder health screening after being swallowed,
- Due to a complex production process, their cost is relatively high,
Handle Neodymium Magnets Carefully
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
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.
Neodymium magnets are highly fragile, they easily break as well as can become damaged.
Neodymium magnets are highly fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Avoid contact with neodymium magnets if you have a nickel allergy.
Studies show a small percentage of people have allergies to certain metals, including 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.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets jump and also clash mutually within a distance of several to around 10 cm from each other.
Do not give neodymium magnets to children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Exercise caution!
