Neodymium flat magnets i.e. MPL 60x10x5 / N38 are magnets made from neodymium in a flat form. They are appreciated for their exceptionally potent magnetic properties, which outshine traditional ferrite magnets.
Thanks to their mighty power, flat magnets are commonly used in products that require exceptional adhesion.
Typical temperature resistance of these magnets is 80°C, but depending on the dimensions, this value grows.
In addition, flat magnets usually have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 60x10x5 / N38 and a magnetic force 9.67 kg with a weight of only 22.50 grams, making it the perfect choice for projects needing a flat magnet.
Neodymium flat magnets offer a range of advantages compared to other magnet shapes, which cause them being a perfect solution for many applications:
Contact surface: Due to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: Their flat shape makes it easier mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers a lot of flexibility in arranging 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 may offer better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet depends on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, may be more appropriate.
Magnets attract objects made of ferromagnetic materials, such as iron elements, nickel, materials with cobalt or alloys of metals with magnetic properties. Additionally, magnets may lesser 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 their magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of magnets creates attractive interactions, which affect materials containing nickel or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Poles of the same kind, such as two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are regularly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
Magnets do not attract plastic, glass items, wood and precious stones. Furthermore, magnets do not affect certain metals, such as copper items, aluminum, copper, aluminum, and 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 exposed to a very strong magnetic field.
It should be noted 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards and even electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense power, 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 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...
  • Due to the option of accurate forming and 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 utilized in HDD drives, electric drive mechanisms, medical devices and very highly developed apparatuses.

Disadvantages of neodymium magnets:

  • They can break 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,
  • 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
  • Potential hazard arising from small pieces of magnets pose a threat, when accidentally ingested, which is crucial in the aspect of protecting young children. Additionally, small elements of these devices can hinder the diagnostic process in case of swallowing.

Handle Neodymium Magnets with Caution

Neodymium magnets can become demagnetized at high temperatures.

Although magnets are generally resilient, 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 primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

In the case of placing a finger in the path of a neodymium magnet, in such a case, a cut or even a fracture may occur.

  Neodymium magnets should not be around youngest children.

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.

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

Magnetic fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

Neodymium magnets are not recommended for 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.

Never bring neodymium magnets close to a phone and GPS.

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

Magnets made of neodymium are particularly delicate, resulting in their breakage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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.

Dust and powder from neodymium magnets are flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

Neodymium magnets are the strongest magnets ever created, and their strength can shock 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.
