Magnetic properties of material N38
Physical properties of NdFeB
Shopping tips
Moreover, although neodymium is a component 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. Interestingly 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 many recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or in solvents, 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 coatings, such as gold, to protect them from external factors and prolong their durability. 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 potential 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 wet conditions, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their tremendous field intensity, neodymium magnets offer the following advantages:
- They have stable power, and over nearly 10 years their performance decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization caused by external magnetic fields,
- In other words, due to the shiny silver coating, the magnet obtains an professional appearance,
- They possess significant magnetic force measurable at the magnet’s surface,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to build),
- Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which expands their functional possibilities,
- Wide application in cutting-edge sectors – they find application in computer drives, rotating machines, diagnostic apparatus or even high-tech tools,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally strengthens its overall robustness,
- Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- They rust in a wet environment. For outdoor use, we recommend using waterproof magnets, such as those made of non-metallic materials,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
- Possible threat due to small fragments may arise, especially if swallowed, which is important in the health of young users. It should also be noted that minuscule fragments from these devices can interfere with diagnostics if inside the body,
- Due to expensive raw materials, their cost is relatively high,
We Recommend Caution with Neodymium Magnets
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can 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.
The magnet is coated with nickel - be careful 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 give neodymium magnets to children.
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.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Neodymium magnetic are incredibly delicate, 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. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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 highly 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.
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.
Neodymium magnets will jump and also touch together within a distance of several to around 10 cm from each other.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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, etc. 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 among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
