They operate thanks to a strong magnetic field that secures massive items, up to several kilograms – depending on the diameter of the magnet used. They are employed in the automotive industry, construction, marketing, or logistics, where they serve well for both permanent and mobile attachment of components.

No! Magnetic holders should not be used for people with implanted cardiac devices, as the strong magnetic field could disrupt their function. For these individuals, we suggest using alternative fastening methods — we offer two such types in our range.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their superior magnetism, neodymium magnets have these key benefits:

Their power is maintained, and after approximately 10 years, it drops only by ~1% (theoretically),
They are very resistant to demagnetization caused by external field interference,
Because of the brilliant layer of silver, the component looks visually appealing,
The outer field strength of the magnet shows elevated magnetic properties,
Thanks to their enhanced temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
Thanks to the possibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which expands their application range,
Wide application in advanced technical fields – they serve a purpose in hard drives, electromechanical systems, clinical machines or even high-tech tools,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of magnetic elements:

They may fracture when subjected to a strong impact. If the magnets are exposed to shocks, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage and additionally increases its overall strength,
High temperatures may significantly reduce the strength of neodymium magnets. Typically, above 80°C, they experience permanent weakening in performance (depending on form). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
They rust in a wet environment, especially when used outside, we recommend using waterproof magnets, such as those made of non-metallic materials,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
Health risk due to small fragments may arise, when consumed by mistake, which is crucial in the family environments. Moreover, tiny components from these magnets may disrupt scanning after being swallowed,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Exercise Caution with Neodymium Magnets

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.

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.

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.

Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.

Neodymium magnets are not toys. You cannot allow them to become toys for children. 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 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.

Neodymium magnets are the strongest magnets ever created, and their power can surprise you.

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.

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

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. Magnets, depending on their size, can even cut off a finger or there can be a severe pressure or a fracture.

Magnets made of neodymium are fragile and can easily crack and shatter.

Neodymium magnets are delicate and will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

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

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, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Exercise caution!
