Cylindrical Neodymium Magnets min. MW 14x2 / N38 are magnets created of neodymium in a cylinder form. They are known for their very strong magnetic properties, which exceed traditional ferrite magnets. Because of their strength, they are frequently used in devices that need strong adhesion. The standard temperature resistance of these magnets is 80 degrees C, but for magnets in a cylindrical form, this temperature increases with their height. Moreover, 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 named MW 14x2 / N38 and a magnetic strength ${capacity} kg weighs only ${weight} grams.
Cylindrical neodymium magnets, also known as Nd2Fe14B, represent the strongest known material for magnet production. Their production process requires a specialized approach and includes melting special neodymium alloys along 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, even though neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a thin layer of nickel to protect them from corrosion. Interestingly 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 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.
In terms of purchasing of cylindrical neodymium magnets, several enterprises offer such products. One of the suggested suppliers is our company Dhit, located in Ożarów Mazowiecki, the address is available directly in the contact tab. It's always worth check the website for the current information and promotions, and before visiting, we recommend calling.
Due to their power, cylindrical neodymium magnets are practical in many applications, they can also pose certain dangers. Because of their strong magnetic power, they can attract metallic objects with great force, which can lead to damaging skin and 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 damage these devices in terms of magnetic recording. Furthermore, neodymium magnets are prone to corrosion in humid environments, therefore they are coated with a thin protective layer. Generally, although they are very useful, one should handle them with due caution.
Neodymium magnets, with the formula Nd2Fe14B, are at this time the strongest available magnets on the market. They are produced through a complicated sintering process, which involves fusing specific alloys of neodymium with additional metals and then forming and heat treating. Their powerful 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 thin coatings, such as epoxy, to shield them from external factors and extend their lifespan. High temperatures exceeding 130°C can result in a loss of their magnetic strength, although there are particular types of neodymium magnets that can withstand temperatures up to 230°C.
As for risks, it is important to avoid using neodymium magnets in acidic conditions, 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 lose their magnetic properties.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

  • They do not lose power over time - after about 10 years, their power decreases by only ~1% (theoretically),
  • They are extremely resistant to demagnetization by external magnetic field,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
  • Significant importance in modern technologies – are utilized in HDD drives, electric drive mechanisms, medical equipment and very modern machines.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Potential hazard to health from tiny fragments of magnets can be dangerous, in case of ingestion, which is particularly important in the context of child safety. Furthermore, small elements of these magnets are able to complicate diagnosis in case of swallowing.

Handle Neodymium Magnets Carefully

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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

  Neodymium magnets should not be in the vicinity children.

Remember that neodymium magnets are not toys. Do not allow children to play 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 can become demagnetized at high temperatures.

Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Neodymium magnets are the most powerful magnets ever created, and their strength can shock you.

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 magnets are extremely fragile, resulting in their cracking.

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.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

Neodymium magnets bounce and also clash mutually within a radius of several to almost 10 cm from each other.

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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

So you are aware of why neodymium magnets are so dangerous, read the article titled How very dangerous are strong neodymium magnets?.
