Neodymium Cylindrical Magnets min. MW 100x10 / N38 are magnets created of neodymium in a cylinder form. They are valued for their very strong magnetic properties, which exceed traditional ferrite magnets. Because of their power, they are frequently employed in products that need powerful holding. The typical temperature resistance of these magnets is 80 degrees C, but for cylindrical magnets, this temperature increases with their height. Moreover, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to increase their durability to corrosion. The shape of a cylinder is also one of the most popular among neodymium magnets. The magnet designated MW 100x10 / N38 and a magnetic strength ${capacity} kg weighs only ${weight} 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 with other metals such as iron and boron. After appropriate processing, such as heat and mechanical treatment, the magnets become ready for use in many 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 thin layer of silver to increase their durability. 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 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 always certain.

Regarding the purchase of cylindrical neodymium magnets, many companies 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 visit the website for the latest information and promotions, and before visiting, we recommend calling.

Due to their strength, cylindrical neodymium magnets are very useful in various applications, they can also constitute certain dangers. Due to their strong magnetic power, they can attract metallic objects with uncontrolled force, which can lead to damaging skin or other surfaces, especially 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 protective layer. In short, although they are handy, they should be handled carefully.

Neodymium magnets, with the formula Nd₂Fe₁₄B, are presently the 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 unmatched magnetic strength comes from the exceptional production technology and chemical composition.
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 gold, to protect them from environmental factors and prolong their durability. Temperatures exceeding 130°C can result in a reduction of their magnetic properties, although there are specific types of neodymium magnets that can withstand temperatures up to 230°C.
As for 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 water, oil, or in an environment containing hydrogen, as they may forfeit 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.
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.

Precautions

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.

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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

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

Neodymium magnets are not recommended for people with pacemakers.

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.

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.

Magnets may crack or alternatively crumble with careless joining to each other. Remember not to move them to each other or hold them firmly in hands at a distance less than 10 cm.

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

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnetic are highly susceptible to damage, resulting in breaking.

Neodymium magnets are characterized by considerable fragility. Magnets made of neodymium 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.

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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

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

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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.
