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 prone to corrosion in humid environments. For this reason, they are coated with a coating of gold-nickel 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 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. Furthermore, they can damage 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 shield them from external factors and extend their lifespan. Temperatures exceeding 130°C can cause a loss of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for dangers, 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 lose their magnetic strength.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit extremely 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 various forms and dimensions, which amplifies their universality in usage.
- Significant importance in the industry of new technologies – find application in hard drives, electric drive mechanisms, medical equipment and very advanced devices.
Disadvantages of neodymium magnets:
- They can break 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 at the same time 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- 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 to health from tiny fragments of magnets are risky, in case of ingestion, which is crucial in the context of child safety. Furthermore, small elements of these magnets can be problematic in medical diagnosis when they are in the body.
Precautions
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. Be cautious and make sure no child plays 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.
Keep neodymium magnets away from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency 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 injuries.
In the situation of placing a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.
Neodymium magnetic are delicate as well as can easily crack as well as get damaged.
Neodymium magnets are fragile and will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets produce strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Avoid contact with neodymium magnets if you have a nickel 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are the strongest magnets ever invented. Their power 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.
So you are aware of why neodymium magnets are so dangerous, see the article titled How very dangerous are powerful neodymium magnets?.
