Neodymium Cylindrical Magnets i.e. MW 9.5x1 / N38 are magnets made of neodymium in a cylinder form. They are valued for their very strong magnetic properties, which exceed traditional iron magnets. Thanks to their strength, they are frequently employed in products that require powerful holding. The standard 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 often applied to the surface of neodymium magnets to enhance their durability to corrosion. The shape of a cylinder is as well very popular among neodymium magnets. The magnet with the designation MW 9.5x1 / N38 and a magnetic force 0.53 kg weighs only 0.53 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 a series of processes, 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 a component of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a thin layer 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, 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 many 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 damage data on magnetic cards and hard drives, although data deletion using a neodymium magnet is not guaranteed.
In terms of purchasing of cylindrical neodymium magnets, many companies 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 check the website for the latest information as well as promotions, and before visiting, please call.
Although, cylindrical neodymium magnets are practical in various applications, they can also constitute certain risk. Due to their strong magnetic power, they can pull metallic objects with uncontrolled force, which can lead to damaging skin or other materials, especially fingers. 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 prone to corrosion in humid environments, thus they are coated with a thin e.g., nickel layer. Generally, although they are handy, one should handle them carefully.
Neodymium magnets, with the formula neodymium-iron-boron, are at this time the strongest available magnets on the market. They are produced through a advanced sintering process, which involves melting 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 sensitive to corrosion, especially in conditions of high humidity. Therefore, they are often covered with coatings, such as silver, to protect them from environmental factors and extend their lifespan. High temperatures exceeding 130°C can cause a deterioration of their magnetic properties, although there are particular 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 environments, 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 lose their magnetic strength.

Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose power over time - after 10 years, their power decreases by only ~1% (theoretically),
  • They are highly 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 form) 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.
  • Significant importance in advanced technologically fields – are used in computer drives, electric motors, medical devices or various technologically advanced devices.

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 metal holder. 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 power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape 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 can be dangerous, when accidentally ingested, which is particularly important in the context of children's health. Furthermore, tiny parts of these products are able to be problematic in medical diagnosis in case of swallowing.

Be Cautious with Neodymium Magnets

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

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

Keep neodymium magnets away from 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.

The magnet is coated with nickel - be careful 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.

Magnets made of neodymium are highly delicate, they easily fall apart as well as can crumble.

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. 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.

 Maintain neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

If the joining of neodymium magnets is not controlled, at that time they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should hold them extremely strongly.

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.

Dust and powder from neodymium magnets are highly 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 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.

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

Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
