Neodymium flat magnets i.e. MPL 13x10x5 / N35H are magnets created from neodymium in a rectangular form. They are appreciated for their extremely powerful magnetic properties, which are much stronger than traditional ferrite magnets.
Thanks to their high strength, flat magnets are commonly used in devices that need exceptional adhesion.
Typical temperature resistance of flat magnets is 80°C, but with larger dimensions, this value rises.
Moreover, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their durability.
The magnet with the designation MPL 13x10x5 / N35H i.e. a lifting capacity of 3.38 kg with a weight of a mere 4.88 grams, making it the perfect choice for applications requiring a flat shape.

Neodymium flat magnets provide 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 adjacent parts, which is 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 important for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in placing them in devices, 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, reducing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be more appropriate.

How do magnets work? Magnets attract ferromagnetic materials, such as iron elements, nickel, cobalt and special alloys of ferromagnetic metals. Moreover, magnets may lesser 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 their magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of these objects creates attractive forces, which attract 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, repel each other.
Thanks to this principle of operation, magnets are often used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the materials used.

Magnets do not attract plastics, glass, wood or precious stones. Moreover, magnets do not affect most metals, such as copper items, aluminum, 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 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 and even medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

They do not lose strength over time - after 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field very well,
Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
They have very high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
Wide application in advanced technologically fields – find application in hard drives, electric motors, medical devices or other modern machines.

Disadvantages of neodymium magnets:

They can break when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk to health from tiny fragments of magnets are risky, when accidentally ingested, which becomes significant in the aspect of protecting young children. Additionally, tiny parts of these products are able to complicate diagnosis when they are in the body.

Be Cautious with Neodymium Magnets

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power 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 damage to the magnets.

Dust and powder from neodymium magnets are 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.

It is important to keep neodymium magnets away from children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

Keep neodymium magnets as far away as possible from GPS and smartphones.

Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are incredibly fragile, they easily crack and can become damaged.

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.

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.

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 jump and clash mutually within a distance of several to almost 10 cm from each other.

You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.

The strong magnetic field generated by neodymium magnets can destroy 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. Remember not to place neodymium magnets close to these electronic devices.

Neodymium magnets can become demagnetized at high temperatures.

Even though magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

The magnet coating is made of nickel, so be cautious 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.
