Shopping tips
Moreover, even though neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a thin layer of silver to protect them from corrosion. 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. Therefore, 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 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 susceptible to corrosion, especially in conditions of high humidity. Therefore, they are often covered with thin coatings, such as epoxy, to shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic environments, basic environments, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may lose their magnetic properties.
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They retain their attractive force for nearly ten years – the loss is just ~1% (in theory),
- Their ability to resist magnetic interference from external fields is impressive,
- In other words, due to the glossy nickel coating, the magnet obtains an aesthetic appearance,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- With the right combination of materials, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the structure),
- Thanks to the flexibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which expands their usage potential,
- Significant impact in cutting-edge sectors – they are utilized in HDDs, electric drives, clinical machines or even sophisticated instruments,
- Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to mechanical hits, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture and increases its overall robustness,
- High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent loss in performance (depending on shape). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of rubber for outdoor use,
- The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is difficult,
- Health risk due to small fragments may arise, especially if swallowed, which is notable in the health of young users. Additionally, small elements from these devices may hinder health screening when ingested,
- Due to expensive raw materials, their cost is above average,
Exercise Caution with Neodymium Magnets
Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Neodymium magnets are highly susceptible to damage, resulting in shattering.
Neodymium magnets are highly fragile, 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. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
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 severe cut or even a fracture.
It is important to maintain neodymium magnets out of reach from children.
Remember that neodymium magnets are not toys. Do not allow children to play 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.
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.
Keep neodymium magnets away from the wallet, computer, and TV.
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.
Never bring neodymium magnets close to a phone and 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.
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 become demagnetized at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties 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.
The magnet is coated with nickel - be careful if you have an 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.
