Holders with neodymium magnets for tools are practical solutions for organizing metal accessories in the kitchen, as well as in workshops. Equipped with strong magnets (neodymium), that hold ferromagnetic objects with a strength from 1 kg to 7 kg, depending on their size and quality. Installation can be done using screws or adhesive tape, enabling quick installation on a wall without drilling. In the kitchen, they are ideal for keeping knives, such as knives, spatulas, providing quick access and order. In the workshop, they work great for holding wrenches, screwdrivers, which improves tidiness and safety. Advantages include long-lasting performance, rust protection (especially with stainless steel 304 or 316) and simple maintenance. Selected versions, such as Zeller, come in lengths ranging from 20–60 cm, making it easy to match individual needs. It’s recommended to clean off fine metal particles, because they can accumulate on the surface. Neodymium magnets can be brittle and can disrupt electronic devices, so they should be kept away from electronic devices and magnetic cards. Important: magnets only work with steel objects. It’s advisable to opt for products from trusted manufacturers, like Rig-Tig Magnetic, to ensure high quality and durability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (in laboratory conditions),
They remain magnetized despite exposure to strong external fields,
Because of the reflective layer of silver, the component looks aesthetically refined,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
With the right combination of magnetic alloys, they reach increased thermal stability, enabling operation at or above 230°C (depending on the form),
With the option for tailored forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving application potential,
Key role in new technology industries – they serve a purpose in HDDs, electric drives, healthcare devices or even sophisticated instruments,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of NdFeB magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to shocks, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time enhances its overall robustness,
High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent loss 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,
Magnets exposed to damp air can oxidize. Therefore, for outdoor applications, we recommend waterproof types made of non-metallic composites,
The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is restricted,
Possible threat from tiny pieces may arise, in case of ingestion, which is significant in the protection of children. Furthermore, miniature parts from these products might disrupt scanning if inside the body,
In cases of tight budgets, neodymium magnet cost may be a barrier,

Caution with Neodymium Magnets

Neodymium magnets are incredibly delicate, they easily fall apart as well as can become damaged.

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 are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can shock you.

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

Maintain neodymium magnets far from youngest children.

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.

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 will jump and clash together within a distance of several to around 10 cm from each other.

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.

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

People with pacemakers are advised to avoid neodymium magnets.

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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Exercise caution!
