Cylindrical Neodymium Magnets i.e. MW 14x10 / N38 are magnets created of neodymium in a cylindrical shape. They are known for their extremely powerful magnetic properties, which outperform traditional ferrite magnets. Because of their strength, they are often employed in products that require powerful holding. The typical temperature resistance of such magnets is 80°C, but for cylindrical magnets, this temperature increases with the growth of the magnet. Moreover, various special coatings, such as nickel, gold, or chrome, are often applied to the surface of neodymium magnets to enhance their durability to corrosion. The cylindrical shape is as well very popular among neodymium magnets. The magnet named MW 14x10 / N38 with a magnetic force 7.74 kg weighs only 11.55 grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, are the strongest known material for magnet production. Their production process requires a specialized approach and includes melting special neodymium alloys along with other metals such as iron and boron. After a series of processes, such as heat and mechanical treatment, the magnets become ready for use in varied applications, such as electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, although neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of nickel to protect them from corrosion. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires special caution during their handling. For this reason, any mechanical processing should be done before they are magnetized.

In terms of safety, there are many recommendations regarding the use of these magnets. They should not be used in acidic, basic, organic environments or where solvents are present, as well as in water or oil. Additionally, they can damage data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not always certain.

In terms of purchasing of cylindrical neodymium magnets, several enterprises offer such products. One of the suggested suppliers is our company Dhit, located in Ożarów Mazowiecki, the address is available directly in the contact tab. It is recommended to visit the website for the current information as well as promotions, and before visiting, we recommend calling.

Although, cylindrical neodymium magnets are very useful in various applications, they can also pose certain risk. Because of their significant magnetic power, they can attract metallic objects with significant force, which can lead to damaging skin as well as other materials, especially be careful with fingers. Do not use neodymium magnets near equipment or data storage devices, such as credit cards, as they can damage these devices in terms of magnetic recording. Moreover, neodymium magnets are susceptible to corrosion in humid environments, therefore they are coated with a thin e.g., nickel layer. Generally, although they are handy, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are at this time the strong magnets on the market. They are produced through a complicated sintering process, which involves fusing specific alloys of neodymium with other metals and then forming and heat treating. Their unmatched magnetic strength comes from the unique production technology and chemical structure.
In terms of properties in different environments, neodymium magnets are sensitive to corrosion, especially in conditions of high humidity. Therefore, they are often covered with coatings, such as silver, to shield them from external factors and extend their lifespan. High temperatures exceeding 130°C can result in a deterioration of their magnetic properties, although there are particular types of neodymium magnets that can tolerate temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic conditions, basic environments, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an environment containing hydrogen, as they may forfeit their magnetic strength.

A cylindrical magnet in classes N52 and N50 is a powerful and strong magnetic product designed as a cylinder, that offers high force and versatile application. Very good price, fast shipping, stability and broad range of uses.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They have unchanged lifting capacity, and over nearly ten years their performance decreases symbolically – ~1% (in testing),
Their ability to resist magnetic interference from external fields is impressive,
By applying a bright layer of nickel, the element gains a sleek look,
They exhibit superior levels of magnetic induction near the outer area of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
With the option for fine forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
Wide application in cutting-edge sectors – they serve a purpose in HDDs, electromechanical systems, clinical machines as well as high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in tiny dimensions, which makes them ideal in small systems

Disadvantages of neodymium magnets:

They can break when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall durability,
They lose power at elevated temperatures. Most neodymium magnets experience permanent degradation 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,
Magnets exposed to moisture can degrade. Therefore, for outdoor applications, we recommend waterproof types made of plastic,
The use of a protective casing or external holder is recommended, since machining fine details in neodymium magnets is not feasible,
Health risk linked to microscopic shards may arise, when consumed by mistake, which is important in the family environments. It should also be noted that minuscule fragments from these products may complicate medical imaging after being swallowed,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Magnetic strength at its maximum – what it depends on?

The given pulling force of the magnet corresponds to the maximum force, determined in the best circumstances, specifically:

with mild steel, used as a magnetic flux conductor
having a thickness of no less than 10 millimeters
with a polished side
in conditions of no clearance
under perpendicular detachment force
in normal thermal conditions

Determinants of lifting force in real conditions

Practical lifting force is dependent on elements, listed from the most critical to the less significant:

Air gap between the magnet and the plate, since even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Lifting capacity was assessed using a smooth steel plate of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the holding force is lower. In addition, even a minimal clearance {between} the magnet’s surface and the plate lowers the holding force.

Be Cautious with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

Magnets made of neodymium are delicate as well as can easily break as well as get damaged.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.

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.

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

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

It is important to maintain neodymium magnets out of reach from 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 magnets can attract to each other, pinch the skin, and cause significant swellings.

If have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or even a fracture.

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 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.

Exercise caution!
