Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
- Wide application in modern technologies – find application in hard drives, electric motors, medical devices and very modern machines.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Health risk to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. It's also worth noting that miniscule components of these magnets are able to complicate diagnosis after entering the body.
Handle Neodymium Magnets Carefully
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets produce strong magnetic fields that can interfere 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.
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.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic 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 attract to each other, pinch the skin, and cause significant swellings.
If the joining of neodymium magnets is not controlled, then they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should have them very strongly.
Neodymium magnets can demagnetize at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
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.
Keep neodymium magnets away from children.
Neodymium magnets are not toys. Be cautious and make sure no child plays 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 fragile and can easily break as well as get damaged.
Magnets made of neodymium are extremely 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. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
