Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, although neodymium is a component of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a coating 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, 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 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 guaranteed.
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 thin coatings, such as silver, to shield them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a reduction 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 environments, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may lose their magnetic strength.

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- 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,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
- Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which amplifies their universality in usage.
- Wide application in advanced technologically fields – find application in hard drives, electric motors, medical devices and various technologically 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,
- 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 - during 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
- Health risk to health from tiny fragments of magnets can be dangerous, if swallowed, which is particularly important in the context of children's health. Additionally, small elements of these products have the potential to complicate diagnosis after entering the body.
Caution with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Keep neodymium magnets away from 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.
The magnet is coated with nickel. Therefore, exercise caution 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.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are the strongest magnets ever created, and their strength can surprise 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.
Neodymium magnets should not be around youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Keep neodymium magnets away from the wallet, computer, and TV.
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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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.
Neodymium magnets are highly susceptible to damage, leading to shattering.
Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Neodymium magnets will jump and also clash together within a distance of several to around 10 cm from each other.
