Neodymium flat magnets i.e. MPL 13x10x5 / N35H are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which are much stronger than standard iron magnets.
Due to their power, flat magnets are regularly used in structures that need exceptional adhesion.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value rises.
In addition, flat magnets commonly have different coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their durability.
The magnet labeled MPL 13x10x5 / N35H and a magnetic strength 3.38 kg which weighs just 4.88 grams, making it the excellent choice for applications requiring a flat shape.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which lead to them being the best choice for many applications:
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is necessary for their operation.
Mounting: Their flat shape simplifies mounting, especially when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility creators a lot of flexibility in arranging them in structures, which can be 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 depends on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be more appropriate.

Attracted by magnets are ferromagnetic materials, such as iron, nickel, cobalt and special alloys of ferromagnetic metals. Additionally, magnets may lesser affect alloys containing iron, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of the magnetic field, which arises from the ordered movement of electrons in their structure. The magnetic field of magnets creates attractive forces, 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 regularly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the material it is made of.

Magnets do not attract plastic, glass items, wood and most gemstones. Moreover, magnets do not affect certain metals, such as copper items, aluminum materials, 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 under such conditions, the magnet stops being magnetic. Additionally, 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 neodymium plate magnet N50 and N52 is a strong and extremely powerful magnetic piece in the form of a plate, featuring high force and broad usability. Attractive price, 24h delivery, ruggedness and multi-functionality.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They do not lose their power approximately 10 years – the decrease of power is only ~1% (theoretically),
They show exceptional resistance to demagnetization from external magnetic fields,
By applying a shiny layer of nickel, the element gains a modern look,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
Neodymium magnets are known for 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 or adaptation to individual needs – neodymium magnets can be manufactured in multiple variants of geometries, which enhances their versatility in applications,
Wide application in new technology industries – they serve a purpose in data storage devices, electric drives, diagnostic apparatus and high-tech tools,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of rare earth magnets:

They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to physical collisions, it is suggested to place them in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture while also increases its overall strength,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (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,
They rust in a moist environment – during outdoor use, we recommend using encapsulated magnets, such as those made of plastic,
Limited ability to create threads in the magnet – the use of a magnetic holder is recommended,
Safety concern related to magnet particles may arise, especially if swallowed, which is significant in the health of young users. Additionally, small elements from these devices may disrupt scanning when ingested,
High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which may limit large-scale applications

Precautions

The magnet is coated with nickel - be careful if you have an 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Avoid bringing neodymium magnets close to a phone or GPS.

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 can become demagnetized 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.

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.

Magnets are not toys, children should not play with them.

Remember that 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.

Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.

To handle magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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.

If the joining of neodymium magnets is not under control, at that time they may crumble and also crack. You can't approach them to each other. At a distance less than 10 cm you should have them very firmly.

Neodymium magnets are characterized by their fragility, which can cause them to shatter.

Magnets made of neodymium are delicate and will break 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. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

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

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 destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.

People with pacemakers are advised to avoid neodymium magnets.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
