The most recommended mountings for ID badges include options such as this UI 33x13x4 [C311] / N38. They guarantee durability and an aesthetic appearance. Magnetic holders are acknowledged as the best because they do not damage clothing, are easy to install, and provide strong badge attachment. A model equipped with potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is particularly suggested.

No!, magnetic holders are contraindicated for individuals with implanted cardiac devices, as the strong magnetic field can affect their functioning. In such cases, it is suggested 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 strength, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field extremely well,
By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the form) 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 many variants of shapes or sizes, which amplifies their universality in usage.
Significant importance in the industry of new technologies – are used in HDD drives, electric motors, medical devices or very highly developed apparatuses.

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, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
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,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Potential hazard to health from tiny fragments of magnets pose a threat, if swallowed, which becomes significant in the context of child safety. It's also worth noting that tiny parts of these magnets are able to be problematic in medical diagnosis after entering the body.

Handle with Care: Neodymium Magnets

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.

Do not bring neodymium magnets close to GPS and smartphones.

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.

Magnets made of neodymium are extremely fragile, leading to shattering.

Neodymium magnets are characterized by significant fragility. Neodymium magnets 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.

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

Neodymium magnets are the strongest magnets ever invented. 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.

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

Neodymium magnets generate strong 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 videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

If 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.

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.

Neodymium magnets can demagnetize 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.

Neodymium magnets should not be in the vicinity children.

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.

Be careful!

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous very strong neodymium magnets.
