Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their superior holding force, neodymium magnets have these key benefits:
- They do not lose their even during nearly 10 years – the loss of strength is only ~1% (theoretically),
- They remain magnetized despite exposure to magnetic noise,
- In other words, due to the metallic nickel coating, the magnet obtains an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- With the right combination of magnetic alloys, they reach increased thermal stability, enabling operation at or above 230°C (depending on the structure),
- The ability for precise shaping and adaptation to individual 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 serve a purpose in computer drives, electric motors, diagnostic apparatus as well as technologically developed systems,
- 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 powerful impact. If the magnets are exposed to physical collisions, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and reinforces its overall durability,
- Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (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,
- They rust in a humid environment, especially when used outside, we recommend using sealed magnets, such as those made of plastic,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing threads directly in the magnet,
- Potential hazard from tiny pieces may arise, if ingested accidentally, which is notable in the protection of children. Moreover, minuscule fragments from these devices have the potential to interfere with diagnostics if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Handle with Care: Neodymium Magnets
The magnet is coated with nickel. Therefore, exercise caution 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.
Avoid bringing neodymium magnets close to a phone or GPS.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets produce strong magnetic fields that can interfere with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Dust and powder from neodymium magnets are 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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets jump and also clash mutually within a radius of several to around 10 cm from each other.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets produce intense magnetic fields that can destroy 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.
Keep neodymium magnets far from youngest children.
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.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can shock 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 can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Magnets made of neodymium are noted for their fragility, which can cause them to shatter.
Magnets made of neodymium are extremely delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable 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.
Exercise caution!
