Neodymium flat magnets i.e. MPL 3x3x2 / N38 are magnets made from neodymium in a rectangular form. They are valued for their extremely powerful magnetic properties, which are much stronger than ordinary ferrite magnets.
Thanks to their high strength, flat magnets are frequently used in products that require strong holding power.
Most common temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value grows.
In addition, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 3x3x2 / N38 i.e. a magnetic force 0.47 kg with a weight of only 0.14 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets offer a range of advantages versus other magnet shapes, which cause them being the best choice for a multitude of projects:
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often utilized in many devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: This form's flat shape makes it easier mounting, particularly when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators a lot of flexibility in arranging them in devices, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet can offer better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet is dependent on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, are more appropriate.

Attracted by magnets are objects made of ferromagnetic materials, such as iron elements, objects containing nickel, cobalt and special alloys of ferromagnetic metals. Additionally, magnets may weaker affect some other metals, such as steel. Magnets are used in many fields.

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 these objects creates attractive forces, which attract materials containing iron or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Similar poles, such as two north poles, act repelling on each other.
Due to these properties, magnets are regularly used in electrical devices, 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. Moreover, the strength of a magnet depends on its dimensions and the material it is made of.

Not all materials react to magnets, and examples of such substances are plastic, glass, wood and most gemstones. Furthermore, magnets do not affect most metals, such as copper items, aluminum, gold. Although these metals conduct electricity, do not exhibit ferromagnetic properties, meaning that they remain unaffected by a magnet, unless they are subjected to an extremely strong magnetic field.
It should be noted that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that once this temperature is exceeded, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards and even medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

A neodymium plate magnet with classification N52 and N50 is a strong and powerful magnetic product in the form of a plate, featuring high force and universal applicability. Good price, 24h delivery, resistance and universal usability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Besides their durability, neodymium magnets are valued for these benefits:

Their power is durable, and after around 10 years, it drops only by ~1% (according to research),
They protect against demagnetization induced by ambient electromagnetic environments very well,
In other words, due to the shiny gold coating, the magnet obtains an aesthetic appearance,
They exhibit superior levels of magnetic induction near the outer area of the magnet,
Thanks to their exceptional temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
Thanks to the possibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in various configurations, which broadens their usage potential,
Wide application in cutting-edge sectors – they are utilized in hard drives, rotating machines, clinical machines along with other advanced devices,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall strength,
Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Due to corrosion risk in humid conditions, it is advisable to use sealed magnets made of synthetic coating for outdoor use,
Limited ability to create complex details in the magnet – the use of a external casing is recommended,
Potential hazard related to magnet particles may arise, if ingested accidentally, which is important in the family environments. Moreover, tiny components from these magnets might interfere with diagnostics once in the system,
Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications

Safety Guidelines with Neodymium Magnets

Magnets are not toys, children should not play with them.

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.

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.

Under no circumstances should neodymium magnets be brought 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 can demagnetize at high temperatures.

While Neodymium magnets can demagnetize at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

Avoid contact with neodymium magnets if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets away from 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. Remember not to place neodymium magnets close to these electronic devices.

Dust and powder from neodymium magnets are highly 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 among the most powerful magnets on Earth. The surprising force they generate between each other can shock 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 Magnets can attract to each other, pinch the skin, and cause significant swellings.

If have a finger between or on the path of attracting magnets, there may be a large cut or even a fracture.

Magnets made of neodymium are delicate as well as can easily break and shatter.

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. 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.
