Neodymium flat magnets min. MPL 80x40x15 / N38 are magnets made from neodymium in a flat form. They are known for their very strong magnetic properties, which are much stronger than traditional iron magnets.
Due to their strength, flat magnets are regularly applied in structures that need exceptional adhesion.
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 improve their corrosion resistance.
The magnet named MPL 80x40x15 / N38 i.e. a magnetic strength 67.01 kg which weighs just 360 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets offer a range of advantages compared to other magnet shapes, which lead to them being an ideal choice for various uses:
Contact surface: Due to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often applied in many devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: This form's flat shape makes mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in structures, which is more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may offer better stability, minimizing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, like cylindrical or spherical, are a better choice.

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

The operation of magnets is based on the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. Magnetic fields of magnets creates attractive forces, which attract materials containing nickel 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, repel each other.
Due to these properties, magnets are regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.

Not all materials react to magnets, and examples of such substances are plastics, glass items, wood and most gemstones. Furthermore, magnets do not affect most metals, such as copper, 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 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. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

A flat magnet in classes N50 and N52 is a powerful and highly strong metallic component shaped like a plate, that offers strong holding power and versatile application. Good price, fast shipping, stability and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

Their power remains stable, and after around ten years, it drops only by ~1% (according to research),
They are very resistant to demagnetization caused by external magnetic sources,
Because of the reflective layer of gold, the component looks high-end,
They possess strong magnetic force measurable at the magnet’s surface,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
Thanks to the flexibility in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in various configurations, which expands their application range,
Important function in new technology industries – they find application in hard drives, electric drives, diagnostic apparatus as well as other advanced devices,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

They can break when subjected to a powerful impact. If the magnets are exposed to physical collisions, they should be placed in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and reinforces its overall strength,
Magnets lose pulling force when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a moist environment. For outdoor use, we recommend using waterproof magnets, such as those made of plastic,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing complex structures directly in the magnet,
Potential hazard linked to microscopic shards may arise, when consumed by mistake, which is significant in the context of child safety. Moreover, miniature parts from these devices may interfere with diagnostics after being swallowed,
In cases of large-volume purchasing, neodymium magnet cost may be a barrier,

Safety Precautions

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.

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.

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

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

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 made of neodymium are extremely delicate, they easily crack and can crumble.

Neodymium magnetic are delicate as well as 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. 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.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also 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 generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been found 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.

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.

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

Remember that neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.

Pay attention!
