Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, although neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of epoxy to protect them from corrosion. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires care during their handling. For this reason, 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 covered with thin coatings, such as epoxy, to preserve them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can cause a reduction of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic environments, basic conditions, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in wet conditions, oil, or in an environment containing hydrogen, as they may forfeit their magnetic strength.

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 about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains 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...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Wide application in the industry of new technologies – are utilized in hard drives, electric motors, medical equipment or various technologically 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, we recommend 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 strength 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,
- 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Potential hazard associated with microscopic parts of magnets can be dangerous, in case of ingestion, which becomes significant in the aspect of protecting young children. Additionally, tiny parts of these devices are able to be problematic in medical diagnosis in case of swallowing.
Precautions
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other 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 damage to the magnets.
Neodymium magnetic are extremely fragile, resulting in their cracking.
Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets jump and clash mutually within a radius of several to almost 10 cm from each other.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS 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.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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.
Neodymium magnets should not be in the vicinity children.
Remember that 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.
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.
