Shopping tips

The most preferred mountings for ID badges include options such as this UI 45x13x6 [Z323] / N38. They offer security and an aesthetic appearance. Magnetic holders are considered as ideal because they protect clothing, are easy to install, and provide secure badge attachment. A model equipped with potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is especially suggested.
No!, magnetic holders should not be used for individuals with cardiac pacemakers, as the strong magnetic field may interfere with their functioning. For such individuals, it is recommended to use alternative fastening methods, and we offer two such types in our range.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their durability, neodymium magnets are valued for these benefits:

  • They retain their attractive force for around 10 years – the loss is just ~1% (in theory),
  • Their ability to resist magnetic interference from external fields is among the best,
  • By applying a reflective layer of gold, the element gains a modern look,
  • They have exceptional magnetic induction on the surface of the magnet,
  • Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
  • Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which broadens their usage potential,
  • Important function in cutting-edge sectors – they are used in data storage devices, electric motors, diagnostic apparatus as well as high-tech tools,
  • Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,

Disadvantages of NdFeB magnets:

  • They may fracture when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall robustness,
  • They lose power at increased temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • Magnets exposed to wet conditions can degrade. Therefore, for outdoor applications, we suggest waterproof types made of non-metallic composites,
  • Limited ability to create complex details in the magnet – the use of a external casing is recommended,
  • Safety concern from tiny pieces may arise, in case of ingestion, which is crucial in the context of child safety. It should also be noted that miniature parts from these products might complicate medical imaging when ingested,
  • Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle Neodymium Magnets with Caution

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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it 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 injuries.

Magnets will attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.

Neodymium magnets can become demagnetized 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.

  Do not give neodymium magnets to youngest children.

Neodymium magnets are not toys. Do not allow children to play 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 noted for being fragile, which can cause them to become damaged.

Neodymium magnetic are highly fragile, and by joining them in an uncontrolled manner, they will break. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

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.

Neodymium magnets are the strongest magnets ever created, and their power can shock you.

Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.

The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Safety rules!
