Flat neodymium magnets min. MPL 15x10x2 / N38 are magnets made from neodymium in a flat form. They are appreciated for their exceptionally potent magnetic properties, which outshine standard ferrite magnets.
Thanks to their high strength, flat magnets are commonly used in devices that need very strong attraction.
Typical temperature resistance of these magnets is 80°C, but with larger dimensions, this value can increase.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet labeled MPL 15x10x2 / N38 and a magnetic force 1.93 kg weighing just 2.25 grams, making it the perfect choice for applications requiring a flat shape.

Neodymium flat magnets offer a range of advantages versus other magnet shapes, which lead to them being a perfect solution for various uses:
Contact surface: Thanks to their flat shape, flat magnets guarantee a larger contact surface with adjacent parts, which is beneficial in applications requiring 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 necessary for their operation.
Mounting: The flat form's flat shape makes it easier mounting, especially when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in arranging them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, minimizing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, may be more appropriate.

How do magnets work? Magnets attract ferromagnetic materials, such as iron, nickel, cobalt or alloys of metals with magnetic properties. Moreover, magnets may lesser 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 is generated by the movement of electric charges within their material. The magnetic field of magnets creates attractive forces, which affect materials containing iron or other magnetic materials.

Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, repel each other.
Due to these properties, 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. Moreover, the strength of a magnet depends on its dimensions and the materials used.

Magnets do not attract plastics, glass, wooden materials or precious stones. Moreover, magnets do not affect most metals, such as copper, aluminum, copper, aluminum, and gold. Although these metals conduct 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 high temperatures can weaken the magnet's effect. The Curie temperature is specific to each type of magnet, meaning that once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

A neodymium magnet of class N52 and N50 is a strong and powerful metal object with the shape of a plate, featuring high force and universal applicability. Competitive price, 24h delivery, resistance and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from their consistent magnetic energy, neodymium magnets have these key benefits:

Their strength remains stable, and after approximately 10 years, it drops only by ~1% (theoretically),
They protect against demagnetization induced by surrounding magnetic influence remarkably well,
The use of a polished nickel surface provides a eye-catching finish,
The outer field strength of the magnet shows advanced magnetic properties,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to form),
Thanks to the flexibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in diverse shapes and sizes, which expands their functional possibilities,
Important function in advanced technical fields – they serve a purpose in HDDs, electric motors, healthcare devices as well as high-tech tools,
Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to physical collisions, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from damage and additionally increases its overall resistance,
They lose power at high temperatures. Most neodymium magnets experience permanent degradation 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 wet conditions can degrade. Therefore, for outdoor applications, we recommend waterproof types made of plastic,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
Health risk due to small fragments may arise, when consumed by mistake, which is important in the family environments. Moreover, miniature parts from these assemblies have the potential to complicate medical imaging when ingested,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Handle with Care: Neodymium Magnets

Neodymium magnetic are particularly fragile, resulting in their breakage.

Neodymium magnets are characterized by significant fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

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 are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.

In the case of holding a finger in the path of a neodymium magnet, in such a case, a cut or a fracture may occur.

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

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.

Do not give neodymium magnets to 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.

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

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

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

Neodymium magnets can become demagnetized at high temperatures.

Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.

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.

Safety precautions!
