Shopping tips

The most preferred holders for ID badges include options such as this UI 45x13x6 [C321] / N38. They ensure security and an aesthetic appearance. Magnetic holders are acknowledged as optimal because they are gentle on clothing, are user-friendly, and provide secure badge attachment. A model using potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is particularly recommended.
No!, magnetic holders are contraindicated for individuals with implanted cardiac devices, as the strong magnetic field can affect their functioning. For such individuals, it is recommended to use clip-on holders, and we offer two such types in our range.

Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They retain their magnetic properties for almost ten years – the drop is just ~1% (according to analyses),
  • Their ability to resist magnetic interference from external fields is among the best,
  • Thanks to the shiny finish and nickel coating, they have an visually attractive appearance,
  • They exhibit elevated levels of magnetic induction near the outer area of the magnet,
  • With the right combination of compounds, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
  • Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which increases their application range,
  • Wide application in advanced technical fields – they are utilized in computer drives, electric motors, medical equipment as well as technologically developed systems,
  • Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which makes them useful in small systems

Disadvantages of magnetic elements:

  • They may fracture when subjected to a strong impact. If the magnets are exposed to shocks, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time reinforces its overall durability,
  • They lose field intensity at extreme temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
  • They rust in a moist environment, especially when used outside, we recommend using sealed magnets, such as those made of non-metallic materials,
  • Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing holes directly in the magnet,
  • Possible threat related to magnet particles may arise, especially if swallowed, which is notable in the protection of children. It should also be noted that miniature parts from these products may complicate medical imaging once in the system,
  • Due to a complex production process, their cost is considerably higher,

Precautions

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

If you have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or even a fracture.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnetic are extremely fragile, leading to their cracking.

Neodymium magnetic are fragile as well as will crack if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Never bring neodymium magnets close to a phone and 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.

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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other 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.

  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.

Neodymium magnets can become demagnetized 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.

Be careful!
