Neodymium Cylindrical Magnets i.e. MW 10x3 / N38 are magnets created of neodymium in a cylinder form. They are valued for their extremely powerful magnetic properties, which exceed traditional iron magnets. Thanks to their strength, they are frequently employed in devices that need strong adhesion. The typical temperature resistance of these magnets is 80°C, but for magnets in a cylindrical form, 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 durability to corrosion. The cylindrical shape is also very popular among neodymium magnets. The magnet with the designation MW 10x3 / N38 and a magnetic force 1.66 kg has a weight of only 1.77 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 sintering 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 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 susceptible to corrosion in humid environments. For this reason, they are coated with a coating of epoxy to increase their durability. It's worth noting that NdFeB neodymium magnets are about 13% lighter than SmCo magnets and, despite their power, easily break, which requires care 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 in solvents, 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 guaranteed.

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

Due to their strength, cylindrical neodymium magnets are practical in various applications, they can also constitute certain risk. Due to their significant magnetic power, they can pull metallic objects with uncontrolled force, which can lead to damaging skin and other surfaces, 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. Furthermore, neodymium magnets are susceptible to corrosion in humid environments, thus they are coated with a thin e.g., nickel layer. In short, although they are very useful, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are at this time the very strong 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 thermal processing. Their amazing magnetic strength comes from the specific production technology and chemical structure.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in humid conditions. Therefore, they are often coated with coatings, such as nickel, to shield them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a loss of their magnetic properties, although there are particular 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 conditions, 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 forfeit their magnetic properties.

A neodymium magnet in classes N52 and N50 is a strong and powerful metal object with the shape of a cylinder, featuring strong holding power and broad usability. Good price, availability, durability 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 virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (according to literature),
They protect against demagnetization induced by surrounding electromagnetic environments effectively,
In other words, due to the glossy silver coating, the magnet obtains an aesthetic appearance,
The outer field strength of the magnet shows elevated magnetic properties,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the magnetic form),
Thanks to the flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in diverse shapes and sizes, which increases their application range,
Significant impact in cutting-edge sectors – they are used in HDDs, electromechanical systems, clinical machines and sophisticated instruments,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of rare earth magnets:

They can break when subjected to a strong impact. If the magnets are exposed to external force, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from cracks and enhances its overall robustness,
Magnets lose magnetic efficiency 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,
Due to corrosion risk in humid conditions, it is recommended to use sealed magnets made of rubber for outdoor use,
Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
Safety concern from tiny pieces may arise, especially if swallowed, which is important in the health of young users. It should also be noted that miniature parts from these magnets might complicate medical imaging after being swallowed,
In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,

Safety Guidelines with Neodymium Magnets

Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.

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.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, 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 Magnets can attract to each other, pinch the skin, and cause significant injuries.

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

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.

Keep neodymium magnets away from the wallet, computer, and TV.

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. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

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.

Neodymium magnetic are particularly delicate, resulting in their breakage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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.

Neodymium magnets should not be near 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.

The magnet is coated with nickel. Therefore, exercise caution 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Exercise caution!
