Flat neodymium magnets i.e. MPL 6x6x6 / N38 are magnets created from neodymium in a flat form. They are valued for their exceptionally potent magnetic properties, which outshine traditional iron magnets.
Due to their strength, flat magnets are frequently used in devices that require very strong attraction.
Most common temperature resistance of these magnets is 80 °C, but with larger dimensions, this value rises.
Additionally, flat magnets often have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet with the designation MPL 6x6x6 / N38 i.e. a magnetic force 2.84 kg with a weight of only 1.62 grams, making it the perfect choice for projects needing a flat magnet.

Neodymium flat magnets present a range of advantages compared to other magnet shapes, which cause them being a perfect solution for many applications:
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often utilized in various devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: Their flat shape simplifies mounting, especially when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows designers greater 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 offer better stability, minimizing the risk of shifting 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, like cylindrical or spherical, may be more appropriate.

How do magnets work? Magnets attract ferromagnetic materials, such as iron elements, nickel, materials with cobalt and alloys of metals with magnetic properties. Moreover, magnets may weaker affect some other metals, 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. Magnetic fields of magnets creates attractive interactions, which attract materials containing iron or other ferromagnetic substances.

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, act repelling on each other.
Thanks to this principle of operation, magnets are regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.

Not all materials react to magnets, and examples of such substances are plastics, glass, wooden materials or precious stones. Furthermore, 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 they are subjected to an extremely 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 under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

A flat magnet in classes N50 and N52 is a strong and extremely powerful magnetic product shaped like a plate, featuring strong holding power and broad usability. Competitive price, 24h delivery, durability and broad range of uses.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their magnetic efficiency, neodymium magnets provide 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 are extremely resistant to demagnetization caused by external magnetic fields,
By applying a reflective layer of nickel, the element gains a clean look,
They have extremely strong magnetic induction on the surface of the magnet,
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 magnetic form),
The ability for custom shaping and adaptation to specific needs – neodymium magnets can be manufactured in multiple variants of geometries, which extends the scope of their use cases,
Wide application in modern technologies – they are used in HDDs, electric drives, diagnostic apparatus or even sophisticated instruments,
Compactness – despite their small size, they deliver powerful magnetism, making them ideal for precision applications

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a strong impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time strengthens its overall resistance,
Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s form). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a humid environment – during outdoor use, we recommend using sealed magnets, such as those made of non-metallic materials,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing threads directly in the magnet,
Health risk due to small fragments may arise, when consumed by mistake, which is notable in the family environments. Moreover, minuscule fragments from these devices might hinder health screening once in the system,
In cases of tight budgets, neodymium magnet cost may not be economically viable,

Handle with Care: Neodymium Magnets

Do not give neodymium magnets to children.

Neodymium magnets are not toys. Be cautious and make sure no child plays 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.

Never bring neodymium magnets close to a phone and GPS.

Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

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

Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.

Neodymium magnets can demagnetize at high temperatures.

Despite the general resilience of magnets, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

Dust and powder from neodymium magnets are highly flammable.

Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.

The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

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.

Magnets will jump and also clash together within a distance of several to almost 10 cm from each other.

Magnets made of neodymium are known for their fragility, which can cause them to crumble.

Magnets made of neodymium are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
