Magnetic strips designed for tools are practical solutions for organizing steel accessories in kitchens, and also in garages. They contain powerful magnets (NdFeB), that hold metal tools with a holding force up to 7 kg, depending on the model. Installation is done via screws or 3M adhesive, which allows easy mounting on a surface without drilling. In cooking areas, they are ideal for storing knives, e.g. knives, spatulas, providing quick access and visual order. In the workshop, they work great for holding wrenches, screwdrivers, which enhances workspace clarity and work safety. Key benefits are long-lasting performance, corrosion resistance (especially with stainless steel 304 or 316) and easy cleaning. Selected versions, such as Wüsthof, come in lengths from 20 cm to 60 cm, allowing customization. It’s recommended to remove metal debris, because they may collect on the surface. Strong magnets are mechanically delicate and can disrupt electronic devices, therefore they should be kept away from electronic devices and magnetic cards. Note: magnets only work with steel objects. It is recommended to choose products from trusted manufacturers, such as Fiskars, to guarantee 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 strength over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field extremely well,
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 hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
Wide application in advanced technologically fields – are utilized in HDD drives, electric drive mechanisms, medical apparatus or very highly developed apparatuses.

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. 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,
Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Potential hazard associated with microscopic parts of magnets can be dangerous, if swallowed, which is particularly important in the context of child safety. Furthermore, miniscule components of these products can be problematic in medical diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.

To handle 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.

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

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

Neodymium magnets produce intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets should not be around 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.

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

Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.

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.

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

Neodymium magnets are extremely fragile, they easily break and can crumble.

Neodymium magnetic are fragile and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and 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.

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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets away from 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.
