Neodymium Cylindrical Magnets min. MW 10x10 / N38 are magnets created of neodymium in a cylinder form. They are known for their extremely powerful magnetic properties, which outperform traditional ferrite magnets. Thanks to their power, they are often used in products that require strong adhesion. The typical temperature resistance of such magnets is 80°C, but for cylindrical magnets, this temperature rises with the growth of the magnet. Additionally, various special coatings, such as nickel, gold, or chrome, are often applied to the surface of neodymium magnets to enhance their resistance to corrosion. The shape of a cylinder is also very popular among neodymium magnets. The magnet with the designation MW 10x10 / N38 with a magnetic force 5.53 kg weighs only 5.89 grams.

Cylindrical neodymium magnets, often referred to as Nd₂Fe₁₄B, represent the strongest known material for magnet production. Their production process requires a specialized approach and includes sintering special neodymium alloys along with other metals such as iron and boron. After appropriate processing, such as heat and mechanical treatment, the magnets are made available for use in varied applications, including 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 coating of nickel to protect them from corrosion. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, are brittle, which requires care during their handling. Therefore, any mechanical processing should be done before they are magnetized.

In terms of safety, there are many recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, and also in water or oil. Additionally, they can distort data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not always certain.

Regarding the purchase of cylindrical neodymium magnets, several enterprises offer such products. One of the recommended 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 and offers, and before visiting, please call.

Although, cylindrical neodymium magnets are very useful in various applications, they can also pose certain risk. Due to 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. One should not use neodymium magnets near electronic devices or data storage devices, such as credit cards, as they can destroy these devices in terms of magnetic recording. Moreover, neodymium magnets are susceptible to corrosion in humid environments, thus they are coated with a thin e.g., nickel layer. Generally, although they are very useful, they should be handled carefully.

Neodymium magnets, with the formula neodymium-iron-boron, are at this time the strongest available magnets on the market. They are produced through a advanced sintering process, which involves melting specific alloys of neodymium with other metals and then shaping and heat treating. Their unmatched magnetic strength comes from the unique production technology and chemical composition.
In terms of properties in different environments, neodymium magnets are sensitive to corrosion, especially in humid conditions. Therefore, they are often coated with thin coatings, such as epoxy, to shield them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can result in a loss of their magnetic properties, although there are specific 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 environments, basic conditions, organic or solvent environments, unless they are adequately insulated. Additionally, their use is not recommended in wet conditions, oil, or in an environment containing hydrogen, as they may lose their magnetic properties.

A cylindrical magnet N50 and N52 is a powerful and strong magnetic piece in the form of a cylinder, that provides strong holding power and versatile application. Good price, availability, stability and broad range of uses.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their long-term stability, neodymium magnets provide the following advantages:

They virtually do not lose power, because even after 10 years, the decline in efficiency is only ~1% (according to literature),
They show exceptional resistance to demagnetization from outside magnetic sources,
Thanks to the polished finish and gold coating, they have an elegant appearance,
They have exceptional magnetic induction on the surface of the magnet,
Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in different geometries, which broadens their usage potential,
Significant impact in new technology industries – they serve a purpose in hard drives, electric motors, healthcare devices as well as high-tech tools,
Thanks to their concentrated strength, small magnets offer high magnetic performance, in miniature format,

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from damage while also enhances its overall resistance,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a wet environment. For outdoor use, we recommend using encapsulated magnets, such as those made of polymer,
Using a cover – such as a magnetic holder – is advised due to the difficulty in manufacturing holes directly in the magnet,
Possible threat linked to microscopic shards may arise, when consumed by mistake, which is significant in the health of young users. Moreover, miniature parts from these devices have the potential to hinder health screening when ingested,
In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Maximum lifting capacity of the magnet – what contributes to it?

The given strength of the magnet means the optimal strength, calculated in ideal conditions, namely:

with mild steel, serving as a magnetic flux conductor
with a thickness of minimum 10 mm
with a refined outer layer
with no separation
under perpendicular detachment force
in normal thermal conditions

Key elements affecting lifting force

The lifting capacity of a magnet depends on in practice key elements, from primary to secondary:

Air gap between the magnet and the plate, because 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.

* Holding force was measured on a smooth steel plate of 20 mm thickness, when a perpendicular force was applied, whereas under parallel forces the lifting capacity is smaller. Additionally, even a minimal clearance {between} the magnet and the plate reduces the lifting capacity.

Handle Neodymium Magnets with Caution

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

Magnets made of neodymium are incredibly fragile, 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. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

People with pacemakers are advised to avoid neodymium magnets.

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.

Do not give neodymium magnets to children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. 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.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Never bring neodymium magnets close to a phone and GPS.

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

The magnet is coated with nickel - be careful 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.

You should maintain neodymium magnets at a safe distance 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

In the situation of placing a finger in the path of a neodymium magnet, in that situation, a cut or a fracture may occur.

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.
