Holders with neodymium magnets designed for tools are convenient solutions for storing steel items in kitchens, as well as in workshops. Equipped with powerful neodymium magnets (neodymium), that hold ferromagnetic objects with a strength up to 7 kg, depending on the model. Installation is done via screws or adhesive tape, which allows easy mounting on a wall even without the need to drill holes. In cooking areas, they are used for storing knives, such as knives, spatulas, providing quick access and order. In the garage, they work great for organizing hand tools, which enhances workspace clarity and work safety. Advantages include durability, corrosion resistance (especially when made of stainless steel 304 or 316) and simple maintenance. Some models, like Wüsthof, come in lengths from 20 cm to 60 cm, allowing customization. It is important to clean off fine metal particles, since they may collect on the surface. Neodymium magnets can be brittle and can disrupt electronic devices, therefore keep them away from electronic devices and magnetic cards. Note: magnets only work with steel objects. It’s advisable to opt for products from trusted manufacturers, such as Fiskars, to ensure high quality and durability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
They have very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which expands the range of their possible uses.
Key role in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical apparatus and very advanced devices.

Disadvantages of neodymium magnets:

They can break as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form 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,
Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger arising from small pieces of magnets pose a threat, if swallowed, which is crucial in the context of child safety. Additionally, small elements of these devices can complicate diagnosis when they are in the body.

Safety Precautions

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Neodymium magnets bounce and touch each other mutually within a radius of several to almost 10 cm from each other.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

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

Do not give neodymium magnets to youngest 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.

Neodymium magnetic are fragile and can easily break 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.

Dust and powder from neodymium magnets are 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 demagnetize at high temperatures.

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

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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

Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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.

Caution!
