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 exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires 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...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
- Wide application in advanced technologically fields – are utilized in hard drives, electric motors, medical apparatus or very advanced devices.
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 also 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 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard arising from small pieces of magnets are risky, when accidentally ingested, which is crucial in the aspect of protecting young children. Additionally, miniscule components of these magnets can be problematic in medical diagnosis in case of swallowing.
Caution with Neodymium Magnets
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
If joining of neodymium magnets is not under control, then they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should have them extremely firmly.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Keep neodymium magnets as far away as possible from GPS and smartphones.
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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
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.
Neodymium magnets can become demagnetized at high temperatures.
While Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
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.
Magnets made of neodymium are fragile and can easily break as well as get damaged.
Magnets made of neodymium are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
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.
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 happens because such devices have a function to deactivate them in a magnetic field.
