Neodymium flat magnets min. MPL 10x10x3 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which are much stronger than traditional iron magnets.
Due to their power, flat magnets are regularly applied in products that need strong holding power.
Typical temperature resistance of these magnets is 80°C, but depending on the dimensions, this value grows.
Additionally, flat magnets often have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their strength.
The magnet labeled MPL 10x10x3 / N38 and a magnetic strength 2.37 kg which weighs just 2.25 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 a multitude of projects:
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often utilized in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: Their flat shape makes mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in devices, which can be 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. However, one should remember that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, are more appropriate.

Attracted by magnets are objects made of ferromagnetic materials, such as iron elements, nickel, materials with cobalt and special alloys of ferromagnetic metals. Additionally, magnets may lesser affect alloys containing iron, such as steel. It’s worth noting that magnets are utilized in various devices and technologies.

Magnets work thanks to 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. Poles of the same kind, such as two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are often used in magnetic technologies, 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. Additionally, 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 items, wooden materials and most gemstones. Additionally, magnets do not affect most metals, such as copper items, aluminum, copper, aluminum, and gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they remain unaffected by a magnet, unless exposed to a very strong magnetic field.
It should be noted 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 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 or electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

A neodymium plate magnet N52 and N50 is a strong and powerful metal object in the form of a plate, that provides high force and versatile application. Very good price, fast shipping, durability and versatility.

Advantages and disadvantages of neodymium magnets NdFeB.

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

Their strength remains stable, and after around 10 years, it drops only by ~1% (theoretically),
They show strong resistance to demagnetization from external field exposure,
Because of the reflective layer of gold, the component looks visually appealing,
They have very high magnetic induction on the surface of the magnet,
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 different geometries, which expands their functional possibilities,
Significant impact in new technology industries – they serve a purpose in data storage devices, electric drives, clinical machines or even sophisticated instruments,
Thanks to their power density, small magnets offer high magnetic performance, in miniature format,

Disadvantages of neodymium magnets:

They may fracture when subjected to a powerful impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks while also enhances its overall durability,
High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, it's best to use waterproof types made of plastic,
Limited ability to create internal holes in the magnet – the use of a housing is recommended,
Potential hazard linked to microscopic shards may arise, especially if swallowed, which is important in the context of child safety. It should also be noted that miniature parts from these products may interfere with diagnostics if inside the body,
In cases of mass production, neodymium magnet cost is a challenge,

We Recommend Caution with Neodymium Magnets

Neodymium magnets are the strongest magnets ever created, and their power can shock you.

Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.

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

Strong magnetic fields emitted by neodymium magnets can damage 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. You should especially avoid placing neodymium magnets near electronic devices.

Avoid contact with neodymium magnets 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 swellings.

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

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

Remember that neodymium magnets are not toys. Do not allow children to play with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even 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.

Neodymium magnets can demagnetize 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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

Neodymium magnetic 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 as well as coated with a shiny nickel plating, they are not as hard as steel. 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.

Do not bring neodymium magnets close to GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
