Magnetic properties of material N38
Physical properties of NdFeB
Shopping tips
Moreover, although neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a thin layer of gold to increase their durability. 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. It is advisable to avoid their use 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 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 thin coatings, such as silver, to shield them from external factors and extend their lifespan. High temperatures exceeding 130°C can result in a loss of their magnetic properties, although there are particular 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 environments, basic conditions, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may forfeit their magnetic strength.
Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from their consistent power, neodymium magnets have these key benefits:
- They retain their attractive force for around ten years – the drop is just ~1% (according to analyses),
- Their ability to resist magnetic interference from external fields is notable,
- By applying a reflective layer of nickel, the element gains a sleek look,
- They possess significant magnetic force measurable at the magnet’s surface,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- The ability for accurate shaping or customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which extends the scope of their use cases,
- Important function in modern technologies – they are used in HDDs, rotating machines, clinical machines and other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of neodymium magnets:
- They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage while also strengthens its overall resistance,
- Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s dimensions). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Magnets exposed to humidity can corrode. Therefore, for outdoor applications, we suggest waterproof types made of rubber,
- Limited ability to create precision features in the magnet – the use of a external casing is recommended,
- Health risk linked to microscopic shards may arise, in case of ingestion, which is notable in the health of young users. Moreover, miniature parts from these assemblies can disrupt scanning when ingested,
- Due to the price of neodymium, their cost is considerably higher,
Safety Precautions
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
It is essential to keep neodymium magnets out of reach from children.
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.
Keep neodymium magnets away from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy 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 can become demagnetized at high temperatures.
Whilst Neodymium magnets can demagnetize 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.
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 bounce and contact together within a distance of several to almost 10 cm from each other.
Keep neodymium magnets away from 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 should not be near people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere 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.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Avoid contact with neodymium magnets if you have a nickel allergy.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.
Neodymium magnetic are delicate as well as can easily break and shatter.
Neodymium magnetic are highly delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.
