Cylindrical Neodymium Magnets min. MW 5x2 / N38 are magnets made of neodymium in a cylindrical shape. They are known 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 standard temperature resistance of these magnets is 80°C, but for cylindrical magnets, 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 cylindrical shape is also very popular among neodymium magnets. The magnet named MW 5x2 / N38 with a magnetic lifting capacity of 0.55 kg weighs only 0.29 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 melting 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, 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 susceptible to corrosion in humid environments. For this reason, they are coated with a thin layer of epoxy 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 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. They should not be used in acidic, basic, organic environments or in solvents, 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.
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 is available directly in the contact tab. It's always worth visit the site for the current information as well as promotions, and before visiting, we recommend calling.
Due to their power, cylindrical neodymium magnets are very useful in various applications, they can also pose certain risk. Due to their strong magnetic power, they can attract metallic objects with uncontrolled force, which can lead to damaging skin and other surfaces, especially hands. Do 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 susceptible to corrosion in humid environments, therefore they are coated with a thin e.g., nickel layer. Generally, although they are very useful, one should handle them with due caution.
Neodymium magnets, with the formula neodymium-iron-boron, are currently the strongest available 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 thermal processing. Their powerful magnetic strength comes from the unique 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 covered with thin coatings, such as silver, to preserve them from external factors and prolong their durability. 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 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 lose their magnetic strength.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense strength, neodymium magnets have the following advantages:

  • They do not lose their strength (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
  • They possess 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 and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
  • Wide application in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical apparatus and various technologically advanced devices.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
  • High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the form and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
  • Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Possible danger to health from tiny fragments of magnets are risky, if swallowed, which is particularly important in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis when they are in the body.

Handle Neodymium Magnets Carefully

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can become demagnetized at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

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

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

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

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.

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 destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

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.

Neodymium magnets will jump and contact together within a radius of several to around 10 cm from each other.

Neodymium magnets are among the strongest magnets on Earth. The astonishing force they generate between each other can shock 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.

Neodymium magnets are noted for their fragility, which can cause them to become damaged.

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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

In order to show why neodymium magnets are so dangerous, see the article - How dangerous are powerful neodymium magnets?.
