Cylindrical Neodymium Magnets i.e. MW 10x1.5 / N38 are magnets created of neodymium in a cylinder form. They are known for their extremely powerful magnetic properties, which exceed ordinary ferrite magnets. Because of their strength, they are frequently used in devices that require strong adhesion. The typical temperature resistance of such magnets is 80 degrees 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 frequently applied to the surface of neodymium magnets to enhance their durability to corrosion. The cylindrical shape is as well very popular among neodymium magnets. The magnet designated MW 10x1.5 / N38 with a magnetic lifting capacity of 0.83 kg has a weight of only 0.88 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 melting special neodymium alloys with other metals such as iron and boron. After a series of processes, such as heat and mechanical treatment, the magnets become ready for use in many 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. Therefore, they are coated with a coating of gold-nickel to protect them from corrosion. 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. For this reason, 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 in solvents, as well as in water or oil. Furthermore, they can damage 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 is recommended to check the website for the current information as well as offers, and before visiting, please call.
Due to their power, cylindrical neodymium magnets are very practical in many applications, they can also pose certain risk. Because of their strong magnetic power, they can pull metallic objects with great force, which can lead to crushing skin or other materials, especially fingers. Do not use neodymium magnets near equipment or data storage devices, such as credit cards, as they can damage these devices in terms of magnetic recording. Furthermore, neodymium magnets are prone to corrosion in humid environments, therefore 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 Nd2Fe14B, are currently the very strong magnets on the market. They are produced through a advanced sintering process, which involves fusing specific alloys of neodymium with other metals and then forming and heat treating. Their unmatched magnetic strength comes from the specific 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 silver, to preserve them from external factors and prolong their durability. Temperatures exceeding 130°C can cause a reduction of their magnetic properties, 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 lose their magnetic strength.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

  • They do not lose power over time - after about 10 years, their power decreases by only ~1% (theoretically),
  • They protect against demagnetization caused by external magnetic field extremely well,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They have very high magnetic induction on the surface of the magnet,
  • By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • The ability for precise shaping and customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Key role in advanced technologically fields – find application in hard drives, electric motors, medical devices or very modern machines.

Disadvantages of neodymium magnets:

  • They can break as they are extremely 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 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 loss 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,
  • 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 arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the aspect of protecting young children. Furthermore, small elements of these products have the potential to complicate diagnosis when they are in the body.

Handle with Care: Neodymium Magnets

Neodymium magnets are noted for being fragile, which can cause them to shatter.

Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets 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.

People with pacemakers are advised to avoid neodymium magnets.

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.

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.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

 Maintain neodymium magnets away from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. 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.

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

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

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets can demagnetize at high temperatures.

Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

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