Neodymium flat magnets min. MPL 60x10x5 / N38 are magnets made from neodymium in a rectangular form. They are known for their very strong magnetic properties, which surpass traditional iron magnets.
Due to their strength, flat magnets are regularly applied in devices that need strong holding power.
Most common temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value rises.
Additionally, flat magnets usually have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 60x10x5 / N38 and a lifting capacity of 9.67 kg with a weight of only 22.50 grams, making it the excellent choice for applications requiring a flat shape.
Neodymium flat magnets present a range of advantages versus other magnet shapes, which lead to them being a perfect solution for many applications:
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: The flat form's flat shape makes it easier mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in placing them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can offer better stability, minimizing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet is dependent on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, are a better choice.
Magnets attract ferromagnetic materials, such as iron elements, nickel, materials with cobalt and alloys of metals with magnetic properties. Additionally, magnets may weaker affect some other metals, such as steel. It’s worth noting that magnets are utilized in various devices and technologies.
Magnets work thanks to the properties of the magnetic field, which arises from the ordered movement of electrons in their structure. The magnetic field of these objects creates attractive forces, which affect materials containing iron or other magnetic materials.

Magnets have two poles: north (N) and south (S), which interact with each other when they are different. Poles of the same kind, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size and the materials used.
Magnets do not attract plastics, glass, wooden materials or most gemstones. Additionally, magnets do not affect certain metals, such as copper, aluminum, items made of gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless they are subjected to an extremely strong magnetic field.
It’s worth noting that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.

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

  • They do not lose strength over time - after about 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 glossy nickel, gold, or silver finish, 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 high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
  • 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 enhances their versatility in applications.
  • Significant importance in modern technologies – find application in HDD drives, electric drive mechanisms, medical devices and very highly developed apparatuses.

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 protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously 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 reduction 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,
  • Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
  • 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
  • Possible danger arising from small pieces of magnets can be dangerous, when accidentally ingested, which is crucial in the context of children's health. It's also worth noting that small elements of these devices have the potential to hinder the diagnostic process when they are in the body.

Exercise Caution with Neodymium Magnets

Neodymium magnetic are delicate and can easily break and shatter.

Neodymium magnets are characterized by considerable fragility. Neodymium magnetic 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.

Do not place neodymium magnets near a computer HDD, TV, and wallet.

Neodymium magnets produce strong magnetic fields that 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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

Magnets will crack or crumble with uncontrolled joining to each other. You can't approach them to each other. At a distance less than 10 cm you should have them extremely firmly.

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

Neodymium magnets can become demagnetized 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.

Never bring neodymium magnets close to a phone and 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.

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

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.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.

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.

Neodymium magnets are the most powerful, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
