Neodymium Cylindrical Magnets min. MW 24x6 / N38 are magnets created of neodymium in a cylindrical shape. They are valued for their very strong magnetic properties, which exceed ordinary ferrite magnets. Thanks to their strength, they are often used in products that require powerful holding. The standard temperature resistance of such magnets is 80°C, but for cylindrical magnets, this temperature increases with their height. Additionally, various special coatings, such as nickel, gold, or chrome, are often 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 24x6 / N38 and a magnetic lifting capacity of 7.96 kg has a weight of only 20.36 grams.
Cylindrical neodymium magnets, often referred to as Nd2Fe14B, are the strongest known material for magnet production. The technology of their production requires a specialized approach and includes melting special neodymium alloys 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 gold 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 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 in solvents, 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.
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's always worth check the website for the latest information as well as offers, and before visiting, please call.
Due to their strength, cylindrical neodymium magnets are practical in many applications, they can also pose certain dangers. Due to their strong magnetic power, they can pull metallic objects with significant force, which can lead to damaging skin and other materials, 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, therefore they are coated with a thin protective layer. Generally, although they are handy, they should be handled with due caution.
Neodymium magnets, with the formula neodymium-iron-boron, are presently the very strong magnets on the market. They are produced through a advanced sintering process, which involves melting special alloys of neodymium with other metals and then forming and heat treating. Their powerful magnetic strength comes from the exceptional production technology and chemical structure.
In terms of properties in different environments, neodymium magnets are susceptible to corrosion, especially in conditions of high humidity. Therefore, they are often coated with thin coatings, such as gold, to protect them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can result in a reduction of their magnetic strength, although there are particular types of neodymium magnets that can withstand temperatures up to 230°C.
As for potential dangers, it is important to avoid using neodymium magnets in acidic environments, basic environments, organic or solvent environments, unless they are properly protected. Additionally, their use is not recommended in wet conditions, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic properties.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose their power (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They are exceptionally resistant to demagnetization caused by an external magnetic field,
  • 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,
  • Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
  • Significant importance in advanced technologically fields – find application in computer drives, electric motors, medical apparatus and other highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a powerful 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 simultaneously increases its overall strength,
  • Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
  • They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • 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
  • Health risk arising from small pieces of magnets pose a threat, in case of ingestion, which is particularly important in the aspect of protecting young children. Furthermore, miniscule components of these magnets can hinder the diagnostic process when they are in the body.

Exercise Caution with Neodymium Magnets

Keep neodymium magnets away from GPS and smartphones.

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.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

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

  Neodymium magnets should not be in the vicinity children.

Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.

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 demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.

To handle 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, leading to breaking.

Neodymium magnetic are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. 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.

Neodymium magnets should not be near people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they 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 magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

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

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.
