Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, even though 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 nickel to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires special caution during their handling. Therefore, 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 where solvents are present, 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 coated with coatings, such as silver, to protect them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can cause a deterioration of their magnetic properties, although there are particular types of neodymium magnets that can tolerate temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic environments, basic environments, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an atmosphere 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 approximately 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 glossy nickel, gold, or silver finish, the element gains an aesthetic appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
- Significant importance in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical equipment and other modern machines.
Disadvantages of neodymium magnets:
- They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. 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 loss in strength (although it is worth noting that this is dependent on the shape 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 recommend 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
- Possible danger arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of child safety. Additionally, miniscule components of these magnets can complicate diagnosis in case of swallowing.
Handle Neodymium Magnets with Caution
Do not give neodymium magnets to children.
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.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
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, try wearing gloves or 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.
If you have a finger between or alternatively on the path of attracting magnets, there may be a large cut or even a fracture.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can 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.
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.
Magnets made of neodymium are known for their fragility, which can cause them to crumble.
Neodymium magnets are characterized by considerable fragility. 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.
