Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable field intensity, neodymium magnets offer the following advantages:
- They have unchanged lifting capacity, and over more than ten years their performance decreases symbolically – ~1% (in testing),
- They protect against demagnetization induced by ambient electromagnetic environments effectively,
- By applying a bright layer of nickel, the element gains a sleek look,
- Magnetic induction on the surface of these magnets is notably high,
- These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for precise shaping or adjustment to individual needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
- Wide application in cutting-edge sectors – they serve a purpose in hard drives, electric drives, diagnostic apparatus or even sophisticated instruments,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to shocks, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage while also strengthens its overall robustness,
- High temperatures may significantly reduce the magnetic power of neodymium magnets. Typically, above 80°C, they experience permanent deterioration in performance (depending on size). 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,
- They rust in a wet environment. If exposed to rain, 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 not feasible,
- Safety concern due to small fragments may arise, in case of ingestion, which is notable in the health of young users. Moreover, minuscule fragments from these devices have the potential to complicate medical imaging after being swallowed,
- Due to the price of neodymium, their cost is relatively high,
Precautions
It is important to maintain neodymium magnets away from 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.
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 attract to each other, pinch the skin, and cause significant injuries.
Magnets attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Keep neodymium magnets as far away as possible from GPS and smartphones.
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 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
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.
Magnets made of neodymium are particularly delicate, which leads to their breakage.
Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnetic 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.
Neodymium magnets are the strongest magnets ever created, and their strength can surprise you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets can demagnetize at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
