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

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

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

They do not lose power over time. After approximately 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field very well,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
They have 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 or customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which expands the range of their possible uses.
Wide application in the industry of new technologies – find application in HDD drives, electric motors, medical equipment or very highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
Magnets lose their power 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 shape 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 recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
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
Potential hazard to health from tiny fragments of magnets can be dangerous, when accidentally ingested, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these devices have the potential to be problematic in medical diagnosis when they are in the body.

Handle Neodymium Magnets with Caution

Magnets made of neodymium are highly delicate, they easily break and can become damaged.

Neodymium magnets are characterized by significant fragility. 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.

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.

Avoid bringing neodymium magnets close to a phone or GPS.

Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

Neodymium magnets are not recommended for 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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

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.

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

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

The magnet is coated with nickel. Therefore, exercise caution if you have an 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets away from 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.

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

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

Safety precautions!

So you are aware of why neodymium magnets are so dangerous, read the article titled How very dangerous are very powerful neodymium magnets?.
