Neodymium flat magnets i.e. MPL 20x10x5 / N38 are magnets created from neodymium in a flat form. They are appreciated for their exceptionally potent magnetic properties, which are much stronger than standard ferrite magnets.
Thanks to their high strength, flat magnets are regularly applied in devices that require exceptional adhesion.
The standard temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value rises.
Additionally, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their strength.
The magnet named MPL 20x10x5 / N38 i.e. a magnetic force 5.58 kg which weighs only 7.5 grams, making it the perfect choice for projects needing a flat magnet.

Neodymium flat magnets provide a range of advantages versus other magnet shapes, which lead to them being the best choice for a multitude of projects:
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: They are often applied in various devices, e.g. 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 there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets allows creators a lot of 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 can provide better stability, minimizing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet depends on the specific project and requirements. In some cases, other shapes, like cylindrical or spherical, may be a better choice.

Magnets attract objects made of ferromagnetic materials, such as iron, nickel, materials with cobalt or alloys of metals with magnetic properties. Additionally, magnets may weaker affect some other metals, such as steel. Magnets are used in many fields.

Magnets work thanks to the properties of their magnetic field, which is generated by the movement of electric charges within their material. The magnetic field of these objects creates attractive forces, which affect materials containing nickel or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, e.g. two north poles, repel each other.
Due to these properties, magnets are often used in electrical devices, e.g. 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 dimensions and the material it is made of.

Not all materials react to magnets, and examples of such substances are plastic, glass items, wood or precious stones. Furthermore, magnets do not affect certain metals, such as copper, aluminum materials, copper, aluminum, and 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 under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards and even medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.

A neodymium plate magnet with classification N52 and N50 is a powerful and strong metal object in the form of a plate, providing high force and broad usability. Competitive price, 24h delivery, ruggedness and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

Apart from their superior magnetism, neodymium magnets have these key benefits:

They virtually do not lose power, because even after 10 years, the performance loss is only ~1% (according to literature),
They remain magnetized despite exposure to magnetic noise,
The use of a mirror-like silver surface provides a refined finish,
Magnetic induction on the surface of these magnets is very strong,
These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
Thanks to the freedom in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which broadens their functional possibilities,
Significant impact in advanced technical fields – they find application in hard drives, rotating machines, diagnostic apparatus and high-tech tools,
Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,

Disadvantages of neodymium magnets:

They are fragile when subjected to a strong impact. If the magnets are exposed to external force, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from cracks and increases its overall resistance,
High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent loss 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,
Magnets exposed to damp air can rust. Therefore, for outdoor applications, it's best to use waterproof types made of non-metallic composites,
Limited ability to create precision features in the magnet – the use of a housing is recommended,
Potential hazard related to magnet particles may arise, especially if swallowed, which is important in the protection of children. It should also be noted that tiny components from these assemblies may disrupt scanning after being swallowed,
In cases of mass production, neodymium magnet cost is a challenge,

Handle with Care: 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 attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, as a major injury may occur. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.

Never bring neodymium magnets close to a phone and GPS.

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

Do not give neodymium magnets to youngest children.

Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.

People with pacemakers are advised to avoid neodymium magnets.

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.

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

Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

Dust and powder from neodymium magnets are highly flammable.

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

Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can surprise you at first.

Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.

Neodymium magnets are known for being fragile, which can cause them to become damaged.

Neodymium magnetic are delicate and 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. At the moment of collision between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets can become demagnetized 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.
