Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, even though neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a thin layer of epoxy to increase their durability. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires special caution during their handling. For this reason, any mechanical processing should be done before they are magnetized.
In terms of safety, there are many recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or in solvents, as well as in water or oil. Additionally, 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 sensitive to corrosion, especially in humid conditions. Therefore, they are often covered with thin coatings, such as epoxy, to shield them from external factors and prolong their durability. High temperatures exceeding 130°C can cause a reduction of their magnetic properties, although there are specific 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 adequately 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 strength, neodymium magnets have the following advantages:
- They do not lose strength over time. After 10 years, their power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They have exceptionally 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 and 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.
- Key role in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical apparatus or very modern machines.
Disadvantages of neodymium magnets:
- 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 at the same time increases its overall strength,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
- 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,
- 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
- Possible danger to health from tiny fragments of magnets can be dangerous, in case of ingestion, which becomes significant in the aspect of protecting young children. Additionally, miniscule components of these products have the potential to be problematic in medical diagnosis in case of swallowing.
Caution with Neodymium Magnets
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise you.
To handle 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 coating is made of nickel, so be cautious 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.
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 attract each other within a distance of several to about 10 cm from each other. Remember not to put 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.
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 can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can damage 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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Neodymium magnets are characterized by their fragility, which can cause them to crumble.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.
