Magnetic holders featuring female thread are versatile accessories, applied in manufacturing as well as everyday uses, such as storage facilities. They consist of a magnetic core, usually neodymium, enclosed within a metal housing, covered with zinc to prevent rusting. The female thread, ranging from M3 to M10, enables insertion of screws, which simplifies installation of various components, such as signs, instruments, or lights. They work via a powerful magnetic zone, which concentrates in the contact area, ensuring load capacity from 1.3 kg to 60 kg, depending on mount size. They are especially useful in the automotive industry, e.g. for attaching car body components, as well as in advertising, for hanging banners. Certain types have a rubber coating, e.g. in black or yellow, helping prevent surface damage and improves moisture resistance. Advantages include high durability, simple mounting due to the internal threading, and the ability to transport heavy ferromagnetic objects. Still, the holding force depends on surface thickness, type of steel, or distance between the holder and the component. Preventing mechanical shocks is crucial, as NdFeB magnets are brittle, and overtightening the screw may be dangerous. In addition, a magnetic zone may interfere with electronics, like phones or data carriers, therefore mounts should be stored away from those devices. It is recommended to choose holders from reputable manufacturers, to guarantee reliability and safety during use.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They retain their magnetic properties for almost 10 years – the drop is just ~1% (in theory),
Their ability to resist magnetic interference from external fields is among the best,
In other words, due to the metallic gold coating, the magnet obtains an aesthetic appearance,
The outer field strength of the magnet shows elevated magnetic properties,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
The ability for custom shaping or adjustment to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
Important function in cutting-edge sectors – they find application in computer drives, electromechanical systems, healthcare devices or even high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which makes them ideal in compact constructions

Disadvantages of neodymium magnets:

They can break when subjected to a heavy impact. If the magnets are exposed to external force, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks and strengthens its overall robustness,
They lose power at high temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of rubber for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
Potential hazard related to magnet particles may arise, especially if swallowed, which is notable in the protection of children. Furthermore, small elements from these devices have the potential to disrupt scanning if inside the body,
High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which may limit large-scale applications

Handle with Care: Neodymium Magnets

Avoid bringing neodymium magnets close to a phone or GPS.

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

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

If the joining of neodymium magnets is not under control, then they may crumble and also crack. You can't move them to each other. At a distance less than 10 cm you should hold them very firmly.

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

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

Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can shock you.

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.

Neodymium magnets can become demagnetized 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.

Neodymium magnets should not be in the vicinity youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.

The magnet coating is made of nickel, so be cautious if you have an 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.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnetic are particularly delicate, resulting in damage.

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 fragments can be propelled in various directions at high speed. Eye protection is recommended.

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.

Warning!
