Neodymium flat magnets i.e. MPL 50x50x25 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which outshine standard iron magnets.
Due to their strength, flat magnets are commonly used in structures that need exceptional adhesion.
The standard temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
Additionally, flat magnets often have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet with the designation MPL 50x50x25 / N38 i.e. a magnetic strength 98.71 kg which weighs only 468.75 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets provide a range of advantages versus other magnet shapes, which cause them being an ideal choice for various uses:
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with other components, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often utilized in various devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: The flat form's flat shape makes it easier 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 greater flexibility in placing them in devices, which is more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet can provide better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the given use and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.

Magnets attract ferromagnetic materials, such as iron, nickel, cobalt or alloys of metals with magnetic properties. 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 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 nickel or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, act repelling on each other.
Thanks to this principle of operation, magnets are commonly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable 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, wood or most gemstones. Furthermore, magnets do not affect certain metals, such as copper items, aluminum, copper, aluminum, and gold. These metals, although they are conductors of 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 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 compasses, credit cards or electronic devices sensitive to magnetic fields. Therefore, it is important to avoid placing magnets near such devices.

A flat magnet N52 and N50 is a powerful and strong magnetic product with the shape of a plate, that provides high force and universal application. Good price, fast shipping, stability and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their exceptional field intensity, neodymium magnets offer the following advantages:

They virtually do not lose strength, because even after ten years, the performance loss is only ~1% (in laboratory conditions),
Their ability to resist magnetic interference from external fields is impressive,
The use of a decorative nickel surface provides a eye-catching finish,
The outer field strength of the magnet shows advanced magnetic properties,
Neodymium magnets are known for strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
Thanks to the possibility in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in various configurations, which expands their application range,
Significant impact in modern technologies – they are utilized in hard drives, rotating machines, medical equipment as well as technologically developed systems,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

They are prone to breaking when subjected to a powerful impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from damage while also reinforces its overall strength,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible field weakening (influenced by the magnet’s dimensions). 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. For outdoor use, we recommend using waterproof magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining multi-axis shapes in neodymium magnets is risky,
Safety concern due to small fragments may arise, especially if swallowed, which is significant in the protection of children. Furthermore, tiny components from these products can disrupt scanning once in the system,
In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Handle with Care: Neodymium Magnets

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Magnets will bounce and touch together within a radius of several to almost 10 cm from each other.

Never bring neodymium magnets close to a phone and GPS.

Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.

It is important to maintain neodymium magnets away from children.

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.

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.

Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise you.

Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.

Neodymium magnetic are highly fragile, they easily fall apart and can crumble.

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. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

Keep neodymium magnets away 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, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.

Keep neodymium magnets away from people with pacemakers.

In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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.

The magnet coating contains nickel, so be cautious if you have a nickel 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.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
