The most preferred holders for ID badges include options such as this UI 33x13x4 [C311] / N38. They ensure resilience and an aesthetic appearance. Magnetic mounts are valued as the best because they protect clothing, are user-friendly, and provide stable badge attachment. A model equipped with efficient neodymium magnets and high-quality adhesive tapes, such as 3M tape, is exceptionally suggested.

No!, magnetic holders are contraindicated for individuals with heart implants, 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.

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

They retain their magnetic properties for nearly 10 years – the loss is just ~1% (based on simulations),
They remain magnetized despite exposure to magnetic noise,
Because of the lustrous layer of gold, the component looks high-end,
They possess strong magnetic force measurable at the magnet’s surface,
With the right combination of materials, they reach significant thermal stability, enabling operation at or above 230°C (depending on the design),
The ability for precise shaping and customization to specific needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
Key role in modern technologies – they are used in hard drives, electric drives, diagnostic apparatus as well as sophisticated instruments,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which makes them useful in miniature devices

Disadvantages of rare earth magnets:

They are fragile when subjected to a powerful 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 damage while also enhances its overall resistance,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (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,
Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of plastic for outdoor use,
Limited ability to create internal holes in the magnet – the use of a housing is recommended,
Health risk related to magnet particles may arise, if ingested accidentally, which is important in the protection of children. Furthermore, miniature parts from these magnets might hinder health screening when ingested,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Safety Precautions

Neodymium magnets should not be in the vicinity youngest children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

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

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Magnets, depending on their size, are able even cut off a finger or there can be a serious pressure or even a fracture.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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 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 magnetic are known for their fragility, which can cause them to crumble.

Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.

Neodymium magnets can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Neodymium magnets should not be near people with pacemakers.

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.

Dust and powder from neodymium magnets are 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.

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

Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Exercise caution!
