Shopping tips
Moreover, although neodymium is a component of the strongest magnets, they are susceptible to corrosion in humid environments. For this reason, they are coated with a coating of gold to protect them from corrosion. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires care during their handling. Therefore, any mechanical processing should be done before they are magnetized.
In terms of safety, there are several recommendations regarding the use of these magnets. They should not be used in acidic, basic, organic environments or in solvents, and also in water or oil. Furthermore, they can distort data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not guaranteed.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in humid conditions. Therefore, they are often coated with coatings, such as gold, to shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are particular types of neodymium magnets that can tolerate temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic conditions, basic conditions, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may lose their magnetic strength.
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have very 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 and the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
- Key role in the industry of new technologies – are used in hard drives, electric motors, medical apparatus and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Health risk arising from small pieces of magnets pose a threat, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that miniscule components of these devices can be problematic in medical diagnosis when they are in the body.
Precautions
Neodymium magnetic are highly fragile, they easily crack and can crumble.
Magnets made of neodymium are extremely delicate, 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 connection between the magnets, sharp metal fragments can be dispersed in different directions.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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 magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise 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.
Neodymium magnets should not be around youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
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 swellings.
In the situation of placing a finger in the path of a neodymium magnet, in that situation, a cut or even a fracture may occur.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Magnetic 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. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, 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.
Neodymium magnets should not be near people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
