Neodymium flat magnets i.e. MPL 10x10x10 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which outshine standard ferrite magnets.
Due to their power, flat magnets are regularly applied in products that require strong holding power.
Most common temperature resistance of these magnets is 80°C, but depending on the dimensions, this value rises.
Additionally, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 10x10x10 / N38 and a lifting capacity of 7.9 kg with a weight of a mere 7.5 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which lead to them being a perfect solution for many applications:
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often used in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators greater flexibility in placing them in devices, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may offer better stability, minimizing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, are more appropriate.

Magnets attract ferromagnetic materials, such as iron, objects containing nickel, cobalt and alloys of metals with magnetic properties. Moreover, magnets may lesser affect some other metals, such as steel. Magnets are used in many fields.

Magnets work thanks to the properties of their magnetic field, which is generated by the movement of electric charges within their material. The magnetic field of magnets creates attractive forces, which affect materials containing cobalt or other magnetic materials.

Magnets have two poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are regularly 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. Moreover, 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, wood or most gemstones. Moreover, magnets do not affect certain metals, such as copper, aluminum materials, items made of gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless they are subjected to an extremely strong magnetic field.
It’s worth noting that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. The Curie temperature is specific to each type of magnet, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

A flat magnet in classes N50 and N52 is a powerful and highly strong magnetic product shaped like a plate, that offers high force and universal application. Competitive price, availability, resistance and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their immense strength, neodymium magnets offer the following advantages:

They virtually do not lose power, because even after ten years, the decline in efficiency is only ~1% (based on calculations),
They show superior resistance to demagnetization from external field exposure,
In other words, due to the shiny gold coating, the magnet obtains an aesthetic appearance,
The outer field strength of the magnet shows advanced magnetic properties,
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 customized forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
Wide application in advanced technical fields – they serve a purpose in computer drives, rotating machines, healthcare devices or even high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in compact dimensions, which allows for use in compact constructions

Disadvantages of NdFeB magnets:

They may fracture when subjected to a heavy impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from breakage and additionally reinforces its overall robustness,
High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on shape). 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,
They rust in a humid environment. If exposed to rain, we recommend using moisture-resistant magnets, such as those made of plastic,
Limited ability to create complex details in the magnet – the use of a mechanical support is recommended,
Possible threat linked to microscopic shards may arise, when consumed by mistake, which is crucial in the health of young users. Furthermore, small elements from these devices have the potential to interfere with diagnostics after being swallowed,
In cases of mass production, neodymium magnet cost is a challenge,

Handle Neodymium Magnets Carefully

Never bring neodymium magnets close to a phone and GPS.

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

Dust and powder from neodymium magnets are 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 should not be in the vicinity children.

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 significant injuries, and even death.

Keep neodymium magnets away from TV, wallet, and computer HDD.

Strong 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. Avoid placing neodymium magnets in close proximity to electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

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.

The magnet coating is made of nickel, so be cautious 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.

Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can shock you.

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

Neodymium magnets can demagnetize at high temperatures.

Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.

Neodymium magnets are delicate as well as can easily break and shatter.

Neodymium magnets are characterized by significant fragility. Magnets made of neodymium are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, sharp metal fragments can be dispersed in different directions.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

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