Neodymium Cylindrical Magnets min. MW 100x10 / N38 are magnets made of neodymium in a cylindrical shape. They are known for their extremely powerful magnetic properties, which exceed traditional iron magnets. Because of their strength, they are often used in devices that require strong adhesion. The typical temperature resistance of these magnets is 80°C, but for magnets in a cylindrical form, this temperature rises with the growth of the magnet. Additionally, various special coatings, such as nickel, gold, or chrome, are often applied to the surface of neodymium magnets to increase their durability to corrosion. The shape of a cylinder is also one of the most popular among neodymium magnets. The magnet designated MW 100x10 / N38 with a magnetic strength 55.29 kg weighs only 589.05 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 a series of processes, such as heat and mechanical treatment, the magnets are made available for use in varied applications, including electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, although neodymium is a component of the strongest magnets, they are prone to corrosion in humid environments. For this reason, they are coated with a coating of gold to increase their durability. 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. 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. It is advisable to avoid their use 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 always certain.
In terms of purchasing of cylindrical neodymium magnets, several enterprises 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 website for the current information as well as promotions, and before visiting, please call.
Although, cylindrical neodymium magnets are very practical in many applications, they can also pose certain risk. Due to their significant magnetic power, they can pull metallic objects with significant force, which can lead to crushing skin and other materials, especially hands. One should 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. Moreover, neodymium magnets are susceptible to corrosion in humid environments, therefore they are coated with a thin protective layer. In short, although they are very useful, they should be handled carefully.
Neodymium magnets, with the formula neodymium-iron-boron, are at this time the strong magnets on the market. They are produced through a advanced sintering process, which involves fusing special alloys of neodymium with other metals and then shaping and heat treating. Their amazing magnetic strength comes from the exceptional 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 covered with thin coatings, such as silver, 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 tolerate 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 water, oil, or in an environment containing hydrogen, as they may forfeit their magnetic properties.

Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time - after approximately 10 years, their strength decreases by only ~1% (theoretically),
  • They are highly resistant to demagnetization by external magnetic field,
  • In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
  • They have exceptionally 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 form) even at temperatures of 230°C or higher...
  • Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
  • Key role in advanced technologically fields – find application in computer drives, electric motors, medical apparatus and various technologically 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 protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time 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 loss 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,
  • 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 or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
  • Potential hazard associated with microscopic parts of magnets can be dangerous, in case of ingestion, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these devices are able to hinder the diagnostic process in case of swallowing.

Handle Neodymium Magnets with Caution

 It is important to keep neodymium magnets out of reach 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 not recommended for people with pacemakers.

Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can surprise you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

Neodymium magnets can demagnetize at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

If have a finger between or alternatively on the path of attracting magnets, there may be a serious cut or even a fracture.

Avoid bringing neodymium magnets close to a phone or GPS.

Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

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

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. Remember not to place neodymium magnets close to these electronic devices.

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.

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

Neodymium magnetic are particularly delicate, which leads to shattering.

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. 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.
