Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Moreover, even though neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a coating of epoxy 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. 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. They should not be used in acidic, basic, organic environments or where solvents are present, as well as in water or oil. Furthermore, they can damage 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 susceptible to corrosion, especially in conditions of high humidity. Therefore, they are often coated with coatings, such as gold, to shield them from external factors and extend their lifespan. Temperatures exceeding 130°C can cause a loss 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 environments, basic conditions, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in wet conditions, oil, or in an atmosphere containing hydrogen, as they may lose their magnetic properties.

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 strength (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are extremely resistant to demagnetization by external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have 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...
- The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
- Wide application in the industry of new technologies – are utilized in computer drives, electric drive mechanisms, medical devices and very modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. 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 form 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,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Health risk associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of child safety. Additionally, miniscule components of these devices can hinder the diagnostic process when they are in the body.
Handle Neodymium Magnets with Caution
The magnet coating is made of nickel, so be cautious if you have an 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.
Do not place neodymium magnets 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, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these 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 can attract to each other, pinch the skin, and cause significant swellings.
Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or in their path when attract. Magnets, depending on their size, can even cut off a finger or alternatively there can be a severe pressure or a fracture.
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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Do not give neodymium magnets to 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.
Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent damage to the magnets.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Magnets made of neodymium are highly susceptible to damage, leading to shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as 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.
