Flat neodymium magnets min. MPL 50x50x10 / N38 are magnets created from neodymium in a rectangular form. They are valued for their exceptionally potent magnetic properties, which are much stronger than standard iron magnets.
Due to their power, flat magnets are commonly used in products that require very strong attraction.
Most common temperature resistance of these magnets is 80°C, but with larger dimensions, this value can increase.
Moreover, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 50x50x10 / N38 i.e. a magnetic force 39.48 kg which weighs just 187.5 grams, making it the ideal choice for projects needing a flat magnet.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which lead to them being a perfect solution for a multitude of projects:
Contact surface: Due to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape makes it easier mounting, especially when there's a need 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 other shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific application and requirements. In some cases, other shapes, such as cylindrical or spherical, may be a better choice.

How do magnets work? Magnets attract objects made of ferromagnetic materials, such as iron, objects containing nickel, materials with cobalt or special alloys of ferromagnetic metals. Moreover, 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 arises from the ordered movement of electrons in their structure. Magnetic fields of these objects creates attractive forces, 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 oppositely oriented. Similar poles, e.g. two north poles, act repelling on each other.
Due to these properties, magnets are often used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.

Magnets do not attract plastic, glass items, wooden materials and precious stones. Furthermore, magnets do not affect certain metals, such as copper items, aluminum, items made of gold. Although these metals conduct 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. 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, credit cards and even electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

A neodymium plate magnet with classification N52 and N50 is a strong and extremely powerful metal object in the form of a plate, that offers high force and universal application. Good price, fast shipping, stability and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (according to literature),
They remain magnetized despite exposure to magnetic noise,
Thanks to the shiny finish and gold coating, they have an visually attractive appearance,
Magnetic induction on the surface of these magnets is notably high,
With the right combination of materials, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
With the option for fine forming and personalized design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Important function in modern technologies – they serve a purpose in hard drives, rotating machines, clinical machines as well as high-tech tools,
Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,

Disadvantages of NdFeB magnets:

They are fragile when subjected to a sudden impact. If the magnets are exposed to physical collisions, we recommend in a metal holder. The steel housing, in the form of a holder, protects the magnet from damage while also strengthens its overall strength,
They lose power at high temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to moisture can rust. Therefore, for outdoor applications, it's best to use waterproof types made of coated materials,
Limited ability to create threads in the magnet – the use of a magnetic holder is recommended,
Safety concern linked to microscopic shards may arise, in case of ingestion, which is significant in the context of child safety. It should also be noted that miniature parts from these products can interfere with diagnostics after being swallowed,
Due to expensive raw materials, their cost is relatively high,

Exercise Caution with Neodymium Magnets

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 can demagnetize at high temperatures.

Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

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

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.

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

Neodymium magnets jump and also touch each other mutually within a distance of several to around 10 cm from each other.

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 extremely fragile, leading to shattering.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

The magnet is coated with nickel - be careful 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Do not give neodymium magnets to 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.

Avoid bringing neodymium magnets close to a phone or GPS.

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 should not be near 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.
