Cylindrical Neodymium Magnets i.e. MW 35x5 / N38 are magnets made of neodymium in a cylindrical shape. They are valued for their extremely powerful magnetic properties, which outperform traditional ferrite magnets. Because of their strength, they are frequently used in devices that need strong adhesion. The standard temperature resistance of such magnets is 80 degrees C, but for magnets in a cylindrical form, this temperature rises with their height. Additionally, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to enhance their resistance to corrosion. The cylindrical shape is as well very popular among neodymium magnets. The magnet with the designation MW 35x5 / N38 and a magnetic strength ${capacity} kg has a weight of only ${weight} grams.

Cylindrical neodymium magnets, also known as Nd₂Fe₁₄B, represent the strongest known material for magnet production. The technology of their production is complicated 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 are made available for use in many applications, such as 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 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, easily break, which requires special caution during their handling. Therefore, any mechanical processing should be done before they are magnetized.

In terms of safety, there are several 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 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 recommended suppliers is our company Dhit, located in Ożarów Mazowiecki, the address is available directly in the contact tab. It's always worth visit the website for the latest information and offers, and before visiting, we recommend calling.

Due to their power, cylindrical neodymium magnets are very useful in many applications, they can also constitute certain dangers. Because of their significant magnetic power, they can attract metallic objects with uncontrolled force, which can lead to damaging skin as well as other surfaces, especially fingers. One should not use neodymium magnets near electronic devices or data storage devices, such as credit cards, as they can damage these devices in terms of magnetic recording. Moreover, neodymium magnets are prone to corrosion in humid environments, therefore they are coated with a thin protective layer. In short, although they are very useful, one should handle them with due caution.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are currently the strong 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 amazing magnetic strength comes from the specific production technology and chemical composition.
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 thin coatings, such as epoxy, to preserve them from external factors and prolong their durability. High temperatures exceeding 130°C can cause a loss of their magnetic properties, although there are specific types of neodymium magnets that can tolerate temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic conditions, basic conditions, 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 lose their magnetic strength.

Advantages and disadvantages of neodymium magnets

Neodymium magnets, also known as NdFeB magnets, are currently the strongest permanent magnets available on the market. Their exceptional magnetic properties make them suitable for various industries, technologies, and everyday life. Below are the key advantages:

Immense attractive force: Even small neodymium magnets generate a very strong magnetic field.
High coercivity: They are resistant to demagnetization by external magnetic fields.
Wide operating temperature range: Standard neodymium magnets operate up to 80°C, with special versions up to 230°C.
Variety of shapes and sizes: Available in many forms, making them easy to adapt to specific applications.
Relatively low price compared to strength: They offer the best strength-to-price ratio among all magnets.
Longevity: With proper use, they retain their magnetic properties for many years.
Versatility of applications: From electric motors to speakers, separators, toys, and jewelry.

Despite numerous advantages, neodymium magnets also have certain disadvantages to consider:

Brittleness: They are hard but brittle and prone to cracking or chipping upon impact.
Susceptibility to corrosion: They require a protective coating (e.g., nickel, zinc) to prevent rusting.
Limited operating temperature for standard versions: Above the Curie temperature, they lose their magnetic properties.
Strong magnetic field can be dangerous: They can damage electronics, magnetic cards, and pose a risk of attracting metal objects with great force.
Difficulties in mechanical processing: Due to their hardness and brittleness, processing them is complex.

Handle Neodymium Magnets Carefully

Magnets are not toys, youngest should not play with them.

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.

Magnets made of neodymium are fragile and can easily crack as well as shatter.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as 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 can attract to each other, pinch the skin, and cause significant swellings.

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

Neodymium magnets can become demagnetized at high temperatures.

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

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

Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

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

Magnetic 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. Avoid placing neodymium magnets in close proximity to electronic devices.

Keep neodymium magnets away from GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets should not be near 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.

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.
