The most recommended holders for ID badges include options such as this UI 45x13x5 [M301] / N38. They guarantee security and an aesthetic appearance. Magnetic holders are valued as optimal because they are gentle on clothing, are easy to install, and provide secure badge attachment. A model using potent neodymium magnets and high-quality adhesive tapes, such as 3M tape, is exceptionally suggested.

No!, magnetic holders should not be used for individuals with heart implants, as the strong magnetic field may interfere with their functioning. For such individuals, it is recommended to use non-magnetic holders, and we offer two such types in our range.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They do not lose strength over time - after about 10 years, their power decreases by only ~1% (theoretically),
They are extremely resistant to demagnetization by external magnetic field,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
They possess very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
Significant importance in advanced technologically fields – are used in HDD drives, electric drive mechanisms, medical devices or very modern machines.

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time 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,
They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk arising from small pieces of magnets can be dangerous, when accidentally ingested, which is crucial in the context of children's health. It's also worth noting that tiny parts of these magnets can complicate diagnosis in case of swallowing.

Precautions

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

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 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.

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

Neodymium magnets are fragile as well as can easily crack as well as shatter.

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

Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

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.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Neodymium magnets produce intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

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.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium Magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a significant injury may occur. Depending on how large the neodymium magnets are, they can lead to a cut or a fracture.
