Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, although neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of gold-nickel 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 where solvents are present, and also in water or oil. Additionally, 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 thin coatings, such as nickel, to shield them from environmental factors and prolong their durability. High temperatures exceeding 130°C can cause a loss of their magnetic properties, 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 environments, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in water, oil, or in an environment 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 power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Significant importance in the industry of new technologies – find application in hard drives, electric motors, medical apparatus and 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, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
- They lose power 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,
- Due to their susceptibility to corrosion in a humid environment, we suggest 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
- Potential hazard to health from tiny fragments of magnets pose a threat, if swallowed, which is crucial in the aspect of protecting young children. Additionally, miniscule components of these magnets are able to be problematic in medical diagnosis when they are in the body.
Handle Neodymium Magnets with Caution
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
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.
Keep neodymium magnets away from 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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
Magnets made of neodymium are incredibly fragile, they easily fall apart as well as can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. 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.
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.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
If you have a finger between or on the path of attracting magnets, there may be a large cut or even a fracture.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
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.
