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 susceptible to corrosion in humid environments. For this reason, they are coated with a coating of gold 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 special caution during their handling. Therefore, 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, and also in water or oil. Additionally, 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 conditions of high humidity. Therefore, they are often coated with thin coatings, such as gold, to preserve them from external factors and extend their lifespan. High temperatures exceeding 130°C can result in a reduction of their magnetic properties, although there are specific types of neodymium magnets that can withstand 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 properly protected. Additionally, their use is not recommended in wet conditions, oil, or in an environment 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 strength over time - after about 10 years, their strength 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 exhibit 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...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Significant importance in modern technologies – find application in hard drives, electric motors, medical devices and very modern machines.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are 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 also increases its overall strength,
- High temperatures can reduce the power 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,
- 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 arising from small pieces of magnets are risky, when accidentally ingested, which becomes significant in the aspect of protecting young children. It's also worth noting that tiny parts of these devices can hinder the diagnostic process in case of swallowing.
Safety Precautions
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can 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 highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets can demagnetize at high temperatures.
Despite the fact that magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.
Magnets are not toys, youngest should not play with them.
Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
The magnet coating contains nickel, so be cautious 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.
People with pacemakers are advised to avoid neodymium magnets.
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.
Magnets made of neodymium are highly susceptible to damage, resulting in their cracking.
Neodymium magnetic are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets will crack or alternatively crumble with careless joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them extremely strongly.
