Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense power, neodymium magnets have the following advantages:
- They do not lose power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They exhibit very high magnetic induction on the surface of the magnet,
- By using an appropriate combination of materials, they can achieve high 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 many variants of shapes and sizes, which amplifies their universality in usage.
- Significant importance in advanced technologically fields – find application in computer drives, electric drive mechanisms, medical apparatus and other modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful 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 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,
- Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Possible danger arising from small pieces of magnets pose a threat, if swallowed, which is particularly important in the context of children's health. Furthermore, miniscule components of these products are able to be problematic in medical diagnosis in case of swallowing.
Handle with Care: Neodymium Magnets
Neodymium magnets are extremely fragile, leading to breaking.
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. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets can demagnetize at high temperatures.
While Neodymium magnets can demagnetize 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.
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, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
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.
Dust and powder from neodymium magnets are highly 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.
To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.
The magnet is coated with nickel - be careful if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant injuries.
Magnets will attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
