Cylindrical Neodymium Magnets i.e. MW 10x4 / N38 are magnets made of neodymium in a cylinder form. They are known for their extremely powerful magnetic properties, which outperform ordinary ferrite magnets. Because of their strength, they are often used in devices that need strong adhesion. The standard temperature resistance of these magnets is 80 degrees C, but for cylindrical magnets, this temperature rises with their height. 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 one of the most popular among neodymium magnets. The magnet designated MW 10x4 / N38 with a magnetic strength 2.21 kg weighs only 2.36 grams.

Cylindrical neodymium magnets, often referred to as Nd₂Fe₁₄B, are the strongest known material for magnet production. The technology of their production is complicated 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, even though neodymium is part of the strongest magnets, they are prone to corrosion in humid environments. Therefore, they are coated with a thin layer of silver to increase their durability. Interestingly that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, 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 several recommendations regarding the use of these magnets. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, as well as in water or oil. Furthermore, they can distort data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not guaranteed.

Regarding the purchase of cylindrical neodymium magnets, several enterprises offer such products. One of the suggested suppliers is our company Dhit, situated in Ożarów Mazowiecki, the address can be found directly in the contact tab. It is recommended to check the website for the latest information as well as offers, and before visiting, please call.

Although, cylindrical neodymium magnets are practical in various applications, they can also pose certain risk. Because of their strong magnetic power, they can attract metallic objects with uncontrolled force, which can lead to crushing skin and 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 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 handy, they should be handled carefully.

Neodymium magnets, with the formula neodymium-iron-boron, are currently the strongest available magnets on the market. They are produced through a advanced sintering process, which involves fusing specific alloys of neodymium with additional metals and then forming and heat treating. Their unmatched magnetic strength comes from the exceptional production technology and chemical structure.
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 silver, to shield them from external factors and extend their lifespan. High temperatures exceeding 130°C can cause a reduction of their magnetic properties, although there are specific types of neodymium magnets that can tolerate temperatures up to 230°C.
As for dangers, it is important to avoid using neodymium magnets in acidic environments, basic environments, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.

A cylindrical neodymium magnet with classification N52 and N50 is a strong and extremely powerful metallic component with the shape of a cylinder, that offers high force and versatile application. Competitive price, 24h delivery, ruggedness and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

Their magnetic field remains stable, and after approximately ten years, it drops only by ~1% (theoretically),
They are very resistant to demagnetization caused by external magnetic fields,
Thanks to the shiny finish and silver coating, they have an elegant appearance,
Magnetic induction on the surface of these magnets is notably high,
Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
With the option for tailored forming and precise design, these magnets can be produced in various shapes and sizes, greatly improving application potential,
Significant impact in modern technologies – they are utilized in data storage devices, electric drives, clinical machines and other advanced devices,
Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,

Disadvantages of neodymium magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to external force, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also increases its overall durability,
They lose field intensity at increased temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the shape and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
They rust in a wet environment, especially when used outside, we recommend using moisture-resistant magnets, such as those made of polymer,
Limited ability to create internal holes in the magnet – the use of a mechanical support is recommended,
Health risk linked to microscopic shards may arise, if ingested accidentally, which is significant in the health of young users. It should also be noted that miniature parts from these products may complicate medical imaging when ingested,
In cases of large-volume purchasing, neodymium magnet cost may be a barrier,

Exercise Caution with Neodymium Magnets

Dust and powder from neodymium magnets are flammable.

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

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.

Keep neodymium magnets away 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

Neodymium magnetic are fragile as well as can easily break and shatter.

Neodymium magnets are characterized by considerable fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

People with pacemakers are advised to avoid neodymium magnets.

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.

Neodymium magnets can demagnetize at high temperatures.

Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.

Maintain neodymium magnets away from youngest children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

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 jump and touch each other mutually within a radius of several to around 10 cm from each other.
