Neodymium Cylindrical Magnets i.e. MW 70x60 / N38 are magnets made of neodymium in a cylindrical shape. They are known for their very strong magnetic properties, which outperform ordinary iron magnets. Because of their strength, they are often used in products that require strong adhesion. The standard temperature resistance of such magnets is 80°C, but for magnets in a cylindrical form, this temperature rises 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 resistance to corrosion. The cylindrical shape is as well very popular among neodymium magnets. The magnet with the designation MW 70x60 / N38 and a magnetic strength 232.23 kg has a weight of only 1731.80 grams.
Cylindrical neodymium magnets, often referred to as Nd2Fe14B, represent 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, such as electric motors, audio-video equipment, and in the automotive and aerospace industries.
Moreover, although neodymium is part of the strongest magnets, they are susceptible to corrosion in humid environments. Therefore, they are coated with a coating 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, are brittle, which requires special caution 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. 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.
In terms of purchasing 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 visit the website for the latest information and offers, and before visiting, we recommend calling.
Although, cylindrical neodymium magnets are very practical in various applications, they can also constitute certain risk. Due to their strong magnetic power, they can attract metallic objects with great force, which can lead to crushing skin or other surfaces, 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. Furthermore, 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 presently the very strong magnets on the market. They are produced through a advanced sintering process, which involves melting specific 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 humid conditions. Therefore, they are often covered with thin coatings, such as epoxy, to shield them from environmental factors and extend their lifespan. Temperatures exceeding 130°C can cause a deterioration of their magnetic strength, although there are particular 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 environments, organic or solvent environments, unless they are insulated. Additionally, their use is not recommended in wet conditions, oil, or in an environment 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 protect against demagnetization caused by external magnetic sources very well,
  • Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
  • They exhibit extremely high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
  • Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
  • Key role in the industry of new technologies – are utilized in hard drives, electric drive mechanisms, medical apparatus or other highly developed apparatuses.

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 metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
  • They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
  • Health risk arising from small pieces of magnets can be dangerous, in case of ingestion, which is crucial in the context of children's health. Furthermore, miniscule components of these devices can be problematic in medical diagnosis when they are in the body.

Exercise Caution with Neodymium Magnets

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

Neodymium magnets can become demagnetized 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.

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

Neodymium magnets generate intense 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 damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

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

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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 under control, at that time they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should hold them very strongly.

The magnet is coated with nickel - be careful 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.

 It is important to keep neodymium magnets out of reach from youngest children.

Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

Magnets made of neodymium are characterized by their fragility, which can cause them to become damaged.

Magnets made of neodymium are delicate as well as will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
