Neodymium flat magnets min. MPL 40x10x18 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which are much stronger than standard ferrite magnets.
Thanks to their high strength, flat magnets are regularly used in devices that need very strong attraction.
Typical temperature resistance of these magnets is 80°C, but depending on the dimensions, this value grows.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet named MPL 40x10x18 / N38 i.e. a magnetic strength 28.43 kg which weighs only 54 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets offer a range of advantages versus other magnet shapes, which cause them being the best choice for many applications:
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: These magnets are often applied in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: Their flat shape makes it easier mounting, particularly when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in arranging them in devices, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, minimizing the risk of shifting or rotating. However, it's important to note 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.

Magnets attract ferromagnetic materials, such as iron elements, nickel, cobalt and special alloys of ferromagnetic metals. Additionally, 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 the magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of magnets creates attractive interactions, which affect materials containing iron 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, act repelling on each other.
Due to these properties, magnets are often used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.

Magnets do not attract plastic, glass items, wooden materials or precious stones. Furthermore, magnets do not affect certain metals, such as copper, aluminum materials, gold. Although these metals conduct 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 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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

A neodymium plate magnet with classification N52 and N50 is a powerful and highly strong magnetic piece in the form of a plate, providing strong holding power and broad usability. Very good price, 24h delivery, resistance and universal usability.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their even during nearly 10 years – the loss of lifting capacity is only ~1% (according to tests),
They show superior resistance to demagnetization from outside magnetic sources,
Thanks to the polished finish and nickel coating, they have an elegant appearance,
They possess significant magnetic force measurable at the magnet’s surface,
Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
With the option for tailored forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
Wide application in modern technologies – they are used in data storage devices, rotating machines, healthcare devices or even high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which makes them useful in compact constructions

Disadvantages of neodymium magnets:

They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage and additionally enhances its overall strength,
High temperatures may significantly reduce the holding force of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). 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,
Due to corrosion risk in humid conditions, it is common to use sealed magnets made of synthetic coating for outdoor use,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is difficult,
Safety concern related to magnet particles may arise, especially if swallowed, which is significant in the family environments. Furthermore, tiny components from these products may disrupt scanning after being swallowed,
In cases of large-volume purchasing, neodymium magnet cost may not be economically viable,

Be Cautious with Neodymium Magnets

It is important to maintain neodymium magnets out of reach from children.

Remember that neodymium magnets are not toys. Do not allow children to play 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 coating contains nickel, so be cautious 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.

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

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

Neodymium magnets are not recommended for people with pacemakers.

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.

Keep neodymium magnets away from GPS and smartphones.

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

Dust and powder from neodymium magnets are highly flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.

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.

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnetic are characterized by being fragile, which can cause them to crumble.

Neodymium magnets are characterized by significant fragility. Neodymium magnets 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.

Neodymium magnets are the strongest magnets ever invented. Their power can surprise 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.
