Shopping tips

The most recommended holders for ID badges include options such as this UI 45x13x6 [C323] / N38. They guarantee resilience and an aesthetic appearance. Magnetic mounts are acknowledged as the best because they do not damage clothing, are easy to install, and provide secure badge attachment. A model utilizing powerful neodymium magnets and high-quality adhesive tapes, such as 3M tape, is particularly recommended.
No!, magnetic holders should not be used for individuals with implanted cardiac devices, as the strong magnetic field may disrupt their functioning. For such individuals, it is recommended to use non-magnetic holders, and we offer two such types in our range.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their notable power, neodymium magnets have these key benefits:

  • They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (according to literature),
  • They show exceptional resistance to demagnetization from outside magnetic sources,
  • The use of a mirror-like nickel surface provides a eye-catching finish,
  • Magnetic induction on the surface of these magnets is impressively powerful,
  • 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 multiple variants of geometries, which extends the scope of their use cases,
  • Wide application in new technology industries – they find application in computer drives, electromechanical systems, clinical machines as well as sophisticated instruments,
  • Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of rare earth magnets:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, they should be placed in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and increases its overall resistance,
  • High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on form). 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 wise to use sealed magnets made of protective material for outdoor use,
  • Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing threads directly in the magnet,
  • Safety concern from tiny pieces may arise, if ingested accidentally, which is important in the family environments. Furthermore, miniature parts from these assemblies have the potential to interfere with diagnostics when ingested,
  • In cases of mass production, neodymium magnet cost may not be economically viable,

Be Cautious with Neodymium Magnets

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.

The magnet coating contains nickel, so be cautious if you have a nickel 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.

 It is essential to maintain neodymium magnets away 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.

Magnets made of neodymium are characterized by their fragility, which can cause them to shatter.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

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.

Magnets may crack or crumble with careless joining to each other. Remember not to move them to each other or have them firmly in hands at a distance less than 10 cm.

Never bring neodymium magnets close to a phone and GPS.

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise 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.

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. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

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.

Pay attention!
