Flat neodymium magnets i.e. MPL 35x35x10 / N38 are magnets made from neodymium in a rectangular form. They are known for their extremely powerful magnetic properties, which outshine ordinary iron magnets.
Thanks to their mighty power, flat magnets are commonly used in products that require very strong attraction.
Typical temperature resistance of these magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets usually have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their durability.
The magnet named MPL 35x35x10 / N38 and a magnetic strength 27.64 kg with a weight of a mere 91.88 grams, making it the ideal choice for applications requiring a flat shape.
Neodymium flat magnets present a range of advantages compared to other magnet shapes, which make them being a perfect solution for many applications:
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: Their flat shape makes mounting, especially when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators greater flexibility in arranging them in devices, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can offer better stability, reducing the risk of shifting or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.
Attracted by magnets are ferromagnetic materials, such as iron elements, nickel, cobalt and special alloys of ferromagnetic metals. 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 the magnetic field, which is generated by the movement of electric charges within their material. The magnetic field of magnets creates attractive interactions, which affect objects made of cobalt or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are different. 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 magnetic technologies, e.g. 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.
Not all materials react to magnets, and examples of such substances are plastic, glass, wooden materials and most gemstones. Moreover, magnets do not affect most metals, such as copper, aluminum materials, 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 exposed to a very strong magnetic field.
It’s worth noting that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even electronic devices sensitive to magnetic fields. Therefore, it is important to exercise caution when using magnets.

Shopping tips

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 highly resistant to demagnetization by external magnetic field,
  • By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
  • They have exceptionally high magnetic induction on the surface of the magnet,
  • Thanks to their high temperature resistance, they can operate (depending on the form) even 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 amplifies their universality in usage.
  • Significant importance in advanced technologically fields – are used in computer drives, electric drive mechanisms, medical devices or very advanced devices.

Disadvantages of neodymium magnets:

  • They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested 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,
  • They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
  • 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,
  • Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
  • Health risk arising from small pieces of magnets are risky, when accidentally ingested, which becomes significant in the aspect of protecting young children. Additionally, small elements of these magnets are able to hinder the diagnostic process after entering the body.

Exercise Caution with Neodymium Magnets

Neodymium magnets can demagnetize 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.

Do not bring neodymium magnets close to GPS and smartphones.

Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.

Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

Neodymium magnetic are known for being fragile, which can cause them to crumble.

Neodymium magnetic are fragile and will shatter if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

People with pacemakers are advised to avoid neodymium magnets.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.

  Neodymium magnets should not be around 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.

Dust and powder from neodymium magnets are flammable.

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

The magnet coating contains nickel, so be cautious if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.

Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a major injury may occur. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a serious pressure or even a fracture.

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

Strong 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
