The most recommended mountings for ID badges include options such as this UI 33x13x4 [C311] / N38. They offer resilience and an aesthetic appearance. Magnetic holders are acknowledged as the best because they are gentle on clothing, are user-friendly, and provide strong badge attachment. A model using powerful neodymium magnets and high-quality adhesive tapes, such as 3M tape, is exceptionally suggested.

No!, magnetic holders are contraindicated for individuals with cardiac pacemakers, as the strong magnetic field may disrupt their functioning. In such cases, it is suggested to use clip-on holders, and we offer two such types in our range.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

Their power is maintained, and after around 10 years, it drops only by ~1% (theoretically),
Their ability to resist magnetic interference from external fields is among the best,
By applying a reflective layer of nickel, the element gains a modern look,
Magnetic induction on the surface of these magnets is impressively powerful,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
With the option for fine forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
Key role in modern technologies – they find application in computer drives, electric motors, medical equipment as well as technologically developed systems,
Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,

Disadvantages of NdFeB magnets:

They may fracture when subjected to a sudden impact. If the magnets are exposed to shocks, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also strengthens its overall robustness,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s form). 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 advisable to use sealed magnets made of protective material for outdoor use,
Limited ability to create threads in the magnet – the use of a mechanical support is recommended,
Safety concern from tiny pieces may arise, if ingested accidentally, which is crucial in the family environments. Furthermore, miniature parts from these devices can complicate medical imaging if inside the body,
In cases of mass production, neodymium magnet cost is a challenge,

Exercise Caution with Neodymium Magnets

Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets should not be in the vicinity youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Magnets made of neodymium are highly fragile, they easily fall apart and can crumble.

Neodymium magnetic are extremely delicate, and by joining them in an uncontrolled manner, they will break. 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.

The magnet is coated with nickel - be careful if you have an 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.

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.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

In the situation of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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 damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.

Caution!
