Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, although neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. For this reason, 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, are brittle, 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 several recommendations regarding the use of these magnets. They should not be used in acidic, basic, organic environments or in solvents, as well as 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 susceptible to corrosion, especially in conditions of high humidity. Therefore, they are often covered with coatings, such as nickel, to protect them from environmental factors and prolong their durability. High temperatures exceeding 130°C can result in a reduction of their magnetic strength, although there are particular 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 conditions, basic conditions, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic properties.

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
- They have very 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 a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in advanced technologically fields – find application in computer drives, electric drive mechanisms, medical equipment or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously 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
- Health risk arising from small pieces of magnets pose a threat, when accidentally ingested, which becomes significant in the context of children's health. Furthermore, small elements of these magnets have the potential to hinder the diagnostic process in case of swallowing.
Notes with Neodymium Magnets
Magnets made of neodymium are highly fragile, they easily break as well as can become damaged.
Neodymium magnets are characterized by significant fragility. Neodymium magnets 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.
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 damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Keep neodymium magnets as far away as possible from 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.
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 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 highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
Magnets will 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 attract. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their power can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Do not give neodymium magnets to youngest children.
Not all neodymium magnets are toys, so do not let children play with them. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
