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. Therefore, they are coated with a thin layer 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 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 damage 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 humid conditions. Therefore, they are often covered with thin coatings, such as nickel, to preserve them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a deterioration of their magnetic strength, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic environments, basic conditions, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may lose their magnetic properties.

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 about 10 years, their power decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic field,
- By applying a shiny coating of nickel, gold, or silver, the element gains 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 shape) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Key role in modern technologies – find application in HDD drives, electric motors, medical devices and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong 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,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- 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
- Health risk associated with microscopic parts of magnets can be dangerous, when accidentally ingested, which is crucial in the context of child safety. Furthermore, tiny parts of these magnets can complicate diagnosis after entering the body.
Caution with Neodymium Magnets
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
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.
Magnets made of neodymium are highly fragile, they easily fall apart as well as can crumble.
Magnets made of neodymium are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
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 can become demagnetized at high temperatures.
While Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Neodymium magnets should not be near people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets produce intense magnetic fields that can destroy 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.
Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
