Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After approximately 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 very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
- Significant importance in modern technologies – are utilized in HDD drives, electric motors, medical apparatus or very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss 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 - during 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
- Possible danger to health from tiny fragments of magnets pose a threat, if swallowed, which becomes significant in the aspect of protecting young children. Furthermore, small elements of these devices can be problematic in medical diagnosis after entering the body.
Handle with Care: Neodymium Magnets
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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Neodymium magnets are incredibly fragile, they easily break and can crumble.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will break. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
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.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Neodymium magnets jump and clash mutually within a distance of several to almost 10 cm from each other.
Magnets are not toys, youngest should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Keep neodymium magnets away from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
