Cylindrical Neodymium Magnets i.e. MW 14x2 / N38 are magnets created of neodymium in a cylinder form. They are valued for their extremely powerful magnetic properties, which exceed ordinary ferrite magnets. Thanks to their strength, they are often used in devices that require strong adhesion. The typical temperature resistance of such magnets is 80 degrees C, but for magnets in a cylindrical form, this temperature increases with the growth of the magnet. Additionally, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to increase their resistance to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet named MW 14x2 / N38 with a magnetic strength 1.55 kg weighs only 2.31 grams.
Cylindrical neodymium magnets, also known as Nd2Fe14B, are the strongest known material for magnet production. The technology of their production requires a specialized approach 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 many 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 coating of gold-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, are brittle, 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. Furthermore, 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 recommended suppliers is our company Dhit, situated in Ożarów Mazowiecki, the address is available directly in the contact tab. It is recommended to visit the site for the latest information as well as offers, and before visiting, please call.
Although, cylindrical neodymium magnets are very practical in many applications, they can also pose certain risk. Because of their strong magnetic power, they can pull metallic objects with significant force, which can lead to damaging skin as well as other surfaces, especially hands. One should 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. In short, although they are very useful, they should be handled with due caution.
Neodymium magnets, with the formula neodymium-iron-boron, are currently 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 shaping and heat treating. Their unmatched magnetic strength comes from the unique 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 covered with coatings, such as epoxy, to preserve them from external factors and extend their lifespan. High temperatures exceeding 130°C can cause a deterioration 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 conditions, basic conditions, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic strength.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from 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 exceptionally resistant to demagnetization caused by an external magnetic field,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They exhibit extremely high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
  • Wide application in modern technologies – are utilized in computer drives, electric drive mechanisms, medical equipment or other advanced devices.

Disadvantages of neodymium magnets:

  • They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
  • They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Possible danger arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the context of child safety. Furthermore, miniscule components of these devices are able to complicate diagnosis after entering the body.

Be Cautious with Neodymium Magnets

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Keep neodymium magnets away from people with pacemakers.

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.

Neodymium magnetic are particularly fragile, which leads to damage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Avoid bringing neodymium magnets close to a phone or GPS.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

If you have a nickel allergy, avoid contact with neodymium magnets.

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.

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.

  Neodymium magnets should not be around youngest children.

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.

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 will attract each other within a distance of several to about 10 cm from each other. Remember not to put fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, are able even cut off a finger or there can be a severe pressure or even a fracture.

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
