The most recommended mountings for ID badges include options such as this UI 33x13x4 [C311] / N38. They offer durability and an aesthetic appearance. Magnetic holders are considered as ideal because they protect clothing, are simple to mount, and provide secure badge attachment. A model utilizing potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is particularly recommended.

No!, magnetic holders are not recommended for individuals with heart implants, as the strong magnetic field can affect 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.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose power over time. After about 10 years, their strength decreases by only ~1% (theoretically),
They are highly resistant to demagnetization by external magnetic sources,
Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
They have exceptionally high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
Significant importance in the industry of new technologies – find application in hard drives, electric motors, medical equipment or various technologically advanced devices.

Disadvantages of neodymium magnets:

They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
Magnets lose their strength due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Health risk to health from tiny fragments of magnets pose a threat, in case of ingestion, which is crucial in the context of children's health. Additionally, small elements of these magnets have the potential to hinder the diagnostic process when they are in the body.

Safety Precautions

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been found to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

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.

Do not bring neodymium magnets close to GPS and smartphones.

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.

Neodymium magnets are particularly fragile, resulting in damage.

Neodymium magnets are extremely fragile, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard 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.

Magnets are not toys, youngest should not play with them.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Avoid contact with neodymium magnets 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 magnets are the strongest magnets ever created, and their power can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the 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 happens because such devices have a function to deactivate them in a magnetic field.

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

Please see the article - What danger lies in neodymium magnets? You will learn how to handle them properly.
