Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense strength, 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 extremely resistant to demagnetization by external magnetic sources,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
- They possess very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which amplifies their universality in usage.
- Wide application in advanced technologically fields – are utilized in computer drives, electric drive mechanisms, medical devices and very highly developed apparatuses.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- They rust in a humid environment - during 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, in case of ingestion, which is particularly important in the context of child safety. It's also worth noting that miniscule components of these products have the potential to hinder the diagnostic process when they are in the body.
Be Cautious with Neodymium Magnets
Neodymium magnets are the strongest magnets ever created, and their strength 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.
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.
Neodymium magnetic are highly delicate, they easily crack and can become damaged.
Neodymium magnetic are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Do not bring neodymium magnets close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If joining of neodymium magnets is not controlled, at that time they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should hold them extremely firmly.
Keep neodymium magnets away from people with pacemakers.
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.
Keep neodymium magnets away from the wallet, computer, and TV.
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.
Neodymium magnets can demagnetize at high temperatures.
Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Maintain neodymium magnets away from youngest 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.
The magnet is coated with nickel. Therefore, exercise caution if you have an 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.
