The internal thread allows for easy attachment of bolts or other mounting accessories, making them versatile, for example, in attaching plates, tools, or markings. The elastic layer prevents surface damage, which is important for delicate materials, such as coated metal or glass panels.

No! Magnetic holders are contraindicated for people with pacemakers, as the strong magnetic field can affect their function. In such cases, we suggest using non-magnetic holders — we offer two such types in our range.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their high retention, neodymium magnets are valued for these benefits:

They do not lose their even over approximately 10 years – the loss of lifting capacity is only ~1% (according to tests),
They protect against demagnetization induced by ambient magnetic influence remarkably well,
The use of a mirror-like silver surface provides a refined finish,
The outer field strength of the magnet shows remarkable magnetic properties,
Thanks to their enhanced temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
With the option for fine forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
Wide application in advanced technical fields – they are utilized in hard drives, rotating machines, clinical machines and other advanced devices,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which makes them ideal in miniature devices

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and additionally enhances its overall robustness,
Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (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,
They rust in a damp environment – during outdoor use, we recommend using encapsulated magnets, such as those made of rubber,
Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing holes directly in the magnet,
Safety concern from tiny pieces may arise, if ingested accidentally, which is significant in the family environments. Furthermore, tiny components from these devices may complicate medical imaging once in the system,
In cases of tight budgets, neodymium magnet cost is a challenge,

Exercise Caution with Neodymium Magnets

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets can become demagnetized 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 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.

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

Keep neodymium magnets as far away as possible from 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.

Neodymium magnets are characterized by being fragile, which can cause them to crumble.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets should not be around children.

Remember that neodymium magnets are not toys. Do not allow children to play with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to place fingers between magnets or alternatively in their path when they attract. Magnets, depending on their size, can even cut off a finger or alternatively there can be a significant pressure or even a fracture.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Exercise caution!
