Neodymium Cylindrical Magnets i.e. MW 33x30 / N38 are magnets created of neodymium in a cylindrical shape. They are valued for their extremely powerful magnetic properties, which outperform ordinary ferrite magnets. Because of their power, they are often used in devices that require strong adhesion. The typical temperature resistance of such magnets is 80°C, but for magnets in a cylindrical form, this temperature increases with their height. Additionally, various special coatings, such as nickel, gold, or chrome, are frequently applied to the surface of neodymium magnets to increase their durability to corrosion. The shape of a cylinder is as well one of the most popular among neodymium magnets. The magnet named MW 33x30 / N38 and a magnetic lifting capacity of ${capacity} kg has a weight of only ${weight} grams.
Cylindrical neodymium magnets, also known as Nd2Fe14B, represent the strongest known material for magnet production. The technology of their production is complicated 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 coating of gold-nickel to increase their durability. Interestingly 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. It is advisable to avoid their use in acidic, basic, organic environments or where solvents are present, and also 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, several enterprises offer such products. One of the recommended suppliers is our company Dhit, located in Ożarów Mazowiecki, the address can be found directly in the contact tab. It is recommended to check the website for the latest information and offers, and before visiting, we recommend calling.
Although, cylindrical neodymium magnets are very practical in many applications, they can also pose certain risk. Due to their significant magnetic power, they can attract metallic objects with significant force, which can lead to damaging skin as well as other surfaces, 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 susceptible to corrosion in humid environments, thus they are coated with a thin protective layer. Generally, although they are very useful, they should be handled with due caution.
Neodymium magnets, with the formula Nd2Fe14B, are currently 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 thermal processing. Their unmatched magnetic strength comes from the specific production technology and chemical composition.
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 nickel, to preserve them from environmental factors and prolong their durability. Temperatures exceeding 130°C can cause a reduction of their magnetic strength, although there are specific 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 insulated. Additionally, their use is not recommended in water, oil, or in an atmosphere containing hydrogen, as they may forfeit their magnetic properties.

Advantages and 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 power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic sources extremely well,
  • In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
  • They exhibit very high magnetic induction on the surface of the magnet,
  • Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) 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 many variants of shapes or sizes, which amplifies their universality in usage.
  • Significant importance in advanced technologically fields – are used in hard drives, electric motors, medical apparatus and very modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are fragile when subjected to a powerful 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,
  • 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 form 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. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
  • The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Health risk to health from tiny fragments of magnets can be dangerous, in case of ingestion, which is crucial in the context of child safety. Furthermore, miniscule components of these magnets can hinder the diagnostic process after entering the body.

Exercise Caution with Neodymium Magnets

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

Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near 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 bounce and clash mutually within a distance of several to almost 10 cm from each other.

  Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Neodymium magnets should not be near 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.

Avoid bringing neodymium magnets close to a phone or GPS.

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.

Dust and powder from neodymium magnets are 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.

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

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 made of neodymium are highly susceptible to damage, resulting in their cracking.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

Neodymium magnets can become demagnetized at high temperatures.

Despite the general resilience of magnets, 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 invented. Their strength can surprise you.
