Flat neodymium magnets i.e. MPL 10x10x4 / N38 are magnets made from neodymium in a flat form. They are known for their exceptionally potent magnetic properties, which outshine standard ferrite magnets.
Thanks to their high strength, flat magnets are frequently used in structures that require exceptional adhesion.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value grows.
In addition, flat magnets usually have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their durability.
The magnet named MPL 10x10x4 / N38 i.e. a magnetic force 3.16 kg weighing just 3 grams, making it the perfect choice for applications requiring a flat shape.

Neodymium flat magnets present a range of advantages versus other magnet shapes, which lead to them being the best choice for various uses:
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often utilized in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows creators a lot of flexibility in arranging them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In certain 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 application and requirements. In certain cases, other shapes, like cylindrical or spherical, are more appropriate.

How do magnets work? Magnets attract ferromagnetic materials, such as iron elements, nickel, materials with cobalt and 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 the magnetic field, which is generated by the movement of electric charges within their material. The magnetic field of these objects creates attractive interactions, which affect objects made of nickel or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its size and the materials used.

Not all materials react to magnets, and examples of such substances are plastics, glass, wooden materials and precious stones. Additionally, magnets do not affect most metals, such as copper, aluminum, items made of 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. 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, credit cards and even medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

A flat magnet N52 and N50 is a powerful and strong magnetic piece shaped like a plate, that offers strong holding power and universal application. Good price, fast shipping, stability and broad range of uses.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to their magnetic capacity, neodymium magnets provide the following advantages:

They do not lose their even during approximately 10 years – the decrease of lifting capacity is only ~1% (according to tests),
They protect against demagnetization induced by external magnetic influence very well,
By applying a reflective layer of gold, the element gains a clean look,
Magnetic induction on the surface of these magnets is very strong,
These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to profile),
With the option for fine forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
Key role in new technology industries – they are utilized in hard drives, rotating machines, diagnostic apparatus and technologically developed systems,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of rare earth magnets:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to external force, it is advisable to use in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and additionally reinforces its overall resistance,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing fine shapes directly in the magnet,
Potential hazard due to small fragments may arise, in case of ingestion, which is notable in the family environments. Furthermore, small elements from these products might hinder health screening after being swallowed,
Due to a complex production process, their cost is above average,

Handle Neodymium Magnets with Caution

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.

People with pacemakers are advised to avoid neodymium magnets.

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 are the strongest magnets ever invented. Their strength can surprise you.

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

Neodymium magnets are noted for being fragile, which can cause them to become damaged.

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. 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.

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.

Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

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

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

If you have a nickel allergy, avoid contact with neodymium magnets.

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 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 should not be around youngest children.

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.

Exercise caution!
