Flat neodymium magnets min. MPL 15x10x2 / N38 are magnets created from neodymium in a rectangular form. They are appreciated for their very strong magnetic properties, which are much stronger than standard iron magnets.
Thanks to their high strength, flat magnets are regularly applied in products that need strong holding power.
Most common temperature resistance of these magnets is 80°C, but with larger dimensions, this value rises.
Moreover, flat magnets often have different coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their corrosion resistance.
The magnet with the designation MPL 15x10x2 / N38 and a magnetic strength 1.93 kg weighing only 2.25 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets offer a range of advantages versus 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 greater contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: They are often utilized in various devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: The flat form's flat shape simplifies 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 creators a lot of flexibility in placing them in structures, which is more difficult with magnets of other shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, are a better choice.

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

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 attract materials containing iron or other magnetic materials.

Magnets have two poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, such as two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are commonly 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 strong magnetic fields. Moreover, 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 items, aluminum, items made of 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’s worth noting 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. Interestingly, 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 neodymium plate magnet of class N50 and N52 is a strong and extremely powerful magnetic piece with the shape of a plate, that offers high force and universal application. Attractive price, fast shipping, resistance and universal usability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their even during approximately ten years – the loss of lifting capacity is only ~1% (according to tests),
They remain magnetized despite exposure to magnetic surroundings,
In other words, due to the metallic silver coating, the magnet obtains an stylish appearance,
The outer field strength of the magnet shows advanced magnetic properties,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
The ability for precise shaping and adaptation to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
Wide application in cutting-edge sectors – they are used in hard drives, electric motors, clinical machines and technologically developed systems,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of NdFeB magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and enhances its overall durability,
Magnets lose magnetic efficiency when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s structure). 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 synthetic coating for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing holes directly in the magnet,
Potential hazard due to small fragments may arise, when consumed by mistake, which is significant in the family environments. Additionally, tiny components from these assemblies may interfere with diagnostics after being swallowed,
Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications

Safety Precautions

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

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.

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 especially delicate, resulting in their breakage.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

People with pacemakers are advised to avoid neodymium magnets.

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.

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 injuries.

Magnets attract each other within a distance of several to about 10 cm from each other. Remember not to place fingers between magnets or in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or alternatively a fracture.

Neodymium magnets can demagnetize 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.

It is important to keep neodymium magnets away from youngest 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.

The magnet is coated with nickel - be careful if you have an allergy.

Studies show a small percentage of people have allergies to certain metals, including 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.

Never bring neodymium magnets close to a phone and GPS.

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

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
