Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- They do not lose their even during around 10 years – the reduction of strength is only ~1% (based on measurements),
- They remain magnetized despite exposure to strong external fields,
- In other words, due to the metallic silver coating, the magnet obtains an stylish appearance,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
- With the option for tailored forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving design adaptation,
- Key role in modern technologies – they serve a purpose in data storage devices, rotating machines, diagnostic apparatus as well as high-tech tools,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which allows for use in compact constructions
Disadvantages of NdFeB magnets:
- They can break when subjected to a heavy impact. If the magnets are exposed to shocks, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from breakage while also reinforces its overall strength,
- Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
- Limited ability to create precision features in the magnet – the use of a external casing is recommended,
- Safety concern related to magnet particles may arise, when consumed by mistake, which is notable in the family environments. Moreover, small elements from these devices may interfere with diagnostics after being swallowed,
- In cases of mass production, neodymium magnet cost is a challenge,
Handle with Care: Neodymium Magnets
People with pacemakers are advised to avoid neodymium magnets.
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.
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 TV, wallet, and computer HDD.
Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets are particularly fragile, which leads to their breakage.
Neodymium magnets are characterized by significant fragility. Magnets made of neodymium 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 can demagnetize 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.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power 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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
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.
Magnets will 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 major injury may occur. Magnets, depending on their size, can even cut off a finger or there can be a serious pressure or a fracture.
It is essential to maintain neodymium magnets out of reach 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.
