Neodymium magnetic mounts featuring female thread can be versatile accessories, applied across industrial as well as everyday applications, e.g. in automotive. They consist of a magnetic core, usually NdFeB, enclosed within a metal shell, coated with Zn layer to prevent rusting. The internal thread, ranging from M3 to M10, enables mounting bolts, which simplifies installation of different items, like signs, instruments, or lamps. They operate via a strong magnetic field, which concentrates in the contact area, ensuring holding force from 1.3 kg to 60 kg, based on mounting dimensions. They are especially useful in vehicle manufacturing, for example, for attaching car body components, and also in advertising, for hanging banners. Some models come with a rubber shell, e.g. in black or yellow colors, which protects surfaces from scratches and improves moisture resistance. Benefits include great strength, simple mounting due to the internal threading, and the ability to transport heavy ferromagnetic objects. However, the holding force relies on surface thickness, material used, and the gap between holder and object. Preventing mechanical shocks is crucial, as NdFeB magnets are brittle, and overtightening the screw may be dangerous. Moreover, a strong magnetic field may affect electronic devices, such as smartphones or magnetic cards, so holders should be kept away from such equipment. Choosing mounts from trusted suppliers is advised, to guarantee reliability and safety during use.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources very well,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
Key role in advanced technologically fields – are used in computer drives, electric motors, medical equipment and very highly developed apparatuses.

Disadvantages of neodymium magnets:

They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and at the same time increases its overall strength,
High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk arising from small pieces of magnets are risky, in case of ingestion, which becomes significant in the aspect of protecting young children. Furthermore, miniscule components of these devices have the potential to hinder the diagnostic process when they are in the body.

Exercise Caution with Neodymium Magnets

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

Strong 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. Avoid placing neodymium magnets in close proximity to electronic devices.

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

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

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.

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 swellings.

Magnets may crack or alternatively crumble with careless connecting to each other. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.

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.

Magnets should not be treated as toys. Therefore, it is not recommended for 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 can demagnetize at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

Neodymium magnetic are extremely fragile, resulting in their cracking.

Neodymium magnets are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, 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.

Exercise caution!
