Neodymium flat magnets min. MPL 15x10x2 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which outshine standard iron magnets.
Thanks to their mighty power, flat magnets are commonly used in products that need very strong attraction.
Most common temperature resistance of flat magnets is 80°C, but with larger dimensions, this value grows.
Moreover, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet labeled MPL 15x10x2 / N38 i.e. a lifting capacity of 1.93 kg weighing a mere 2.25 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets offer a range of advantages compared to other magnet shapes, which lead to them being an ideal choice for a multitude of projects:
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: This form's flat shape makes it easier mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators a lot of flexibility in arranging them in structures, which is more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.

How do magnets work? Magnets attract objects made of ferromagnetic materials, such as iron elements, nickel, cobalt or special alloys of ferromagnetic metals. Moreover, magnets may weaker affect alloys containing iron, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of the magnetic field, which arises from the ordered movement of electrons in their structure. The magnetic field of magnets creates attractive forces, which attract materials containing nickel or other magnetic materials.

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, repel 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 perfect for applications requiring strong magnetic fields. Additionally, 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 or precious stones. Furthermore, magnets do not affect most metals, such as copper, aluminum materials, 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 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 or electronic devices sensitive to magnetic fields. Therefore, it is important to exercise caution when using magnets.

A neodymium magnet N50 and N52 is a strong and extremely powerful metal object designed as a plate, that offers high force and versatile application. Competitive price, availability, durability and broad range of uses.

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% (based on calculations),
They are highly resistant to demagnetization caused by external magnetic fields,
Because of the reflective layer of silver, the component looks aesthetically refined,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
With the option for tailored forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving design adaptation,
Key role in advanced technical fields – they find application in hard drives, electric motors, diagnostic apparatus and other advanced devices,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

They may fracture when subjected to a heavy impact. If the magnets are exposed to external force, we recommend in a steel housing. The steel housing, in the form of a holder, protects the magnet from fracture and additionally strengthens its overall robustness,
They lose strength at elevated temperatures. Most neodymium magnets experience permanent reduction in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Magnets exposed to damp air can corrode. Therefore, for outdoor applications, we recommend waterproof types 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 related to magnet particles may arise, if ingested accidentally, which is notable in the context of child safety. It should also be noted that miniature parts from these devices can disrupt scanning once in the system,
Due to expensive raw materials, their cost is above average,

Handle Neodymium Magnets with Caution

Neodymium magnets are the strongest, 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.

Maintain neodymium magnets far from children.

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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets can become demagnetized 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.

You should keep neodymium magnets at a safe distance 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Dust and powder from neodymium magnets are highly flammable.

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

Neodymium magnets are incredibly delicate, they easily fall apart and can crumble.

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 collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

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 alternatively on the path of attracting magnets, there may be a large cut or even a fracture.

Be careful!

So that know how strong neodymium magnets are and why they are so dangerous, see the article - Dangerous strong neodymium magnets.
