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 susceptible to corrosion in humid environments. For this reason, they are coated with a thin layer of silver to protect them from corrosion. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, 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, 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 sensitive to corrosion, especially in conditions of high humidity. Therefore, they are often covered with coatings, such as gold, to shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can result in a reduction of their magnetic strength, although there are specific types of neodymium magnets that can tolerate temperatures up to 230°C.
As for dangers, it is important to avoid using neodymium magnets in acidic environments, basic environments, 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 properties.

Advantages and disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose power over time - after 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 coating of nickel, gold, or silver, the element acquires 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...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Significant importance in modern technologies – are utilized in hard drives, electric drive mechanisms, medical apparatus and other modern machines.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful 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 reduction 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,
- 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
- Possible danger associated with microscopic parts of magnets are risky, in case of ingestion, which becomes significant in the context of children's health. It's also worth noting that tiny parts of these devices have the potential to hinder the diagnostic process in case of swallowing.
Handle Neodymium Magnets Carefully
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If joining of neodymium magnets is not controlled, at that time they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should have them extremely firmly.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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. Do not forget to keep neodymium magnets away from these electronic devices.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can shock 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.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Strong 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 should not be in the vicinity 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.
Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
Dust and powder from neodymium magnets are highly 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.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Neodymium magnets are extremely fragile, they easily crack and can become damaged.
Magnets made of neodymium are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
