Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their high retention, neodymium magnets are valued for these benefits:
- They have unchanged lifting capacity, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They show exceptional resistance to demagnetization from external magnetic fields,
- Because of the reflective layer of silver, the component looks aesthetically refined,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- Thanks to their enhanced temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
- Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in diverse shapes and sizes, which increases their application range,
- Important function in modern technologies – they are utilized in computer drives, electric motors, diagnostic apparatus and other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,
Disadvantages of neodymium magnets:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from breakage and strengthens its overall strength,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- They rust in a wet environment, especially when used outside, we recommend using sealed magnets, such as those made of plastic,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is risky,
- Safety concern due to small fragments may arise, especially if swallowed, which is significant in the protection of children. Moreover, small elements from these devices might complicate medical imaging once in the system,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Handle Neodymium Magnets Carefully
Magnets made of neodymium are extremely fragile, leading to their cracking.
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 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.
Neodymium magnets are the most powerful magnets ever invented. Their power can surprise you.
To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
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.
Magnets will crack or crumble with uncontrolled connecting to each other. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.
Never bring neodymium magnets close to a phone and GPS.
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets produce intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
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.
The magnet coating is made of nickel, so be cautious if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
