Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their consistent magnetic energy, neodymium magnets have these key benefits:
- They do not lose their magnetism, even after around ten years – the decrease of strength is only ~1% (theoretically),
- They protect against demagnetization induced by surrounding electromagnetic environments effectively,
- By applying a reflective layer of nickel, the element gains a clean look,
- They have extremely strong magnetic induction on the surface of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for precise shaping as well as adaptation to custom needs – neodymium magnets can be manufactured in multiple variants of geometries, which amplifies their functionality across industries,
- Wide application in new technology industries – they serve a purpose in data storage devices, rotating machines, diagnostic apparatus along with technologically developed systems,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of magnetic elements:
- They may fracture when subjected to a sudden 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 cracks and increases its overall durability,
- Magnets lose pulling force 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,
- Magnets exposed to wet conditions can corrode. Therefore, for outdoor applications, we advise waterproof types made of coated materials,
- Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
- Safety concern linked to microscopic shards may arise, in case of ingestion, which is notable in the protection of children. Additionally, minuscule fragments from these magnets can interfere with diagnostics after being swallowed,
- Due to the price of neodymium, their cost is relatively high,
Safety Guidelines with Neodymium Magnets
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
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.
If joining of neodymium magnets is not controlled, then they may crumble and crack. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.
Keep neodymium magnets as far away as possible from GPS and smartphones.
Neodymium magnets produce strong 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 flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Avoid contact with neodymium magnets if you have a nickel 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.
Neodymium magnets can become demagnetized at high temperatures.
Despite the general resilience of magnets, 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 particularly delicate, resulting in shattering.
Neodymium magnets are characterized by considerable fragility. 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 collision between the magnets, small metal fragments can be dispersed in different directions.
Neodymium magnets should not be around youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in 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 happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnets are the most powerful magnets ever created, and their strength can shock you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Exercise caution!
