Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time. After 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They have exceptionally high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
- Significant importance in modern technologies – are utilized in HDD drives, electric motors, medical devices and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard to health from tiny fragments of magnets can be dangerous, if swallowed, which is crucial in the context of children's health. It's also worth noting that miniscule components of these products have the potential to hinder the diagnostic process after entering the body.
Handle Neodymium Magnets with Caution
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If the joining of neodymium magnets is not under control, at that time they may crumble and crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can damage 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 are the most powerful magnets ever invented. Their power 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.
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.
Do not bring neodymium magnets close to GPS and smartphones.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
The magnet coating contains nickel, so be cautious if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium 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.
Magnets made of neodymium are highly delicate, they easily fall apart and can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
People with pacemakers are advised to avoid neodymium magnets.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.
