Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, although neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of nickel to protect them from corrosion. It's worth noting 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. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, 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 always certain.
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 nickel, to protect them from external factors and prolong their durability. High temperatures exceeding 130°C can result in a deterioration of their magnetic strength, although there are particular 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 conditions, basic conditions, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in wet conditions, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.

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 strength decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic sources extremely well,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They exhibit 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 various forms and dimensions, which enhances their versatility in applications.
- Key role in modern technologies – are utilized in hard drives, electric motors, medical apparatus and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a strong 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 simultaneously increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- 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
- Possible danger associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which becomes significant in the context of child safety. It's also worth noting that tiny parts of these devices have the potential to be problematic in medical diagnosis in case of swallowing.
Handle Neodymium Magnets Carefully
Neodymium magnets are extremely fragile, they easily fall apart as well as can become damaged.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets 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.
The magnet is coated with nickel - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium 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.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Keep neodymium magnets away from 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.
Magnets are not toys, children should not play with them.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.

Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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. Avoid placing neodymium magnets in close proximity to electronic devices.
