Magnetic holders with neodymium magnets featuring an external thread are modern solutions, used in many industries, including construction, agriculture, or assembly technology. The construction is based on a strong neodymium magnet, installed in metal casing protected by an anti-corrosion layer. The external thread in sizes M4–M8 allows installation onto compatible surfaces, which makes it possible to screw in various components. With the help of a focused magnetic field, such mounts provide a pulling strength from 3 to 68 kg, depending on the model and size. Applications of the holders include not only industrial operations and DIY projects. Certain models are equipped with a rubber coating, that safeguards mounted elements from damage and increases grip. Note, however, that neodymium magnets can be fragile and may break under excessive tightening. Careful handling is advised, and holders should be kept away from electronics. To ensure reliability, one should opt for certified products.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their tremendous field intensity, neodymium magnets offer the following advantages:

They retain their full power for around 10 years – the drop is just ~1% (based on simulations),
They remain magnetized despite exposure to magnetic noise,
Because of the reflective layer of nickel, the component looks high-end,
They possess significant magnetic force measurable at the magnet’s surface,
With the right combination of compounds, they reach increased thermal stability, enabling operation at or above 230°C (depending on the design),
With the option for customized forming and targeted design, these magnets can be produced in various shapes and sizes, greatly improving engineering flexibility,
Key role in cutting-edge sectors – they are used in hard drives, rotating machines, healthcare devices along with high-tech tools,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They may fracture when subjected to a sudden impact. If the magnets are exposed to shocks, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and additionally increases its overall robustness,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible power drop (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Magnets exposed to damp air can corrode. Therefore, for outdoor applications, we advise waterproof types made of coated materials,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is risky,
Potential hazard due to small fragments may arise, when consumed by mistake, which is significant in the family environments. Moreover, miniature parts from these magnets might interfere with diagnostics if inside the body,
High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which can restrict large-scale applications

Caution with Neodymium Magnets

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been observed 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

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 injuries.

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

Make sure not to bring neodymium magnets close to the 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. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their strength can shock you.

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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.

Neodymium magnets should not be in the vicinity children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Magnets made of neodymium are delicate as well as can easily crack and shatter.

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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

Neodymium magnets should not be near 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.

Exercise caution!
