Neodymium flat magnets i.e. MPL 50x25x12 / N38 are magnets created from neodymium in a flat form. They are known for their very strong magnetic properties, which are much stronger than standard iron magnets.
Thanks to their high strength, flat magnets are regularly used in devices that require exceptional adhesion.
Typical temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value grows.
In addition, flat magnets commonly have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet labeled MPL 50x25x12 / N38 i.e. a lifting capacity of 33.5 kg weighing a mere 112.5 grams, making it the excellent choice for applications requiring a flat shape.

Neodymium flat magnets present a range of advantages compared to other magnet shapes, which cause them being an ideal choice for various uses:
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: Their flat shape simplifies mounting, particularly when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in arranging them in structures, which can be more difficult with magnets of more complex 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 is dependent on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, are a better choice.

Magnets attract ferromagnetic materials, such as iron, objects containing nickel, materials with cobalt or alloys of metals with magnetic properties. Additionally, magnets may weaker affect alloys containing iron, such as steel. It’s worth noting that magnets are utilized in various devices and technologies.

Magnets work thanks to the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. The magnetic field of magnets creates attractive interactions, which affect objects made of cobalt 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 powerful magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the material it is made of.

Magnets do not attract plastics, glass items, wood and most gemstones. Moreover, magnets do not affect most metals, such as copper, aluminum, copper, aluminum, and gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless exposed to a very strong magnetic field.
It should be noted that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards and even medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

A neodymium plate magnet N52 and N50 is a powerful and highly strong metallic component designed as a plate, that offers high force and universal application. Good price, 24h delivery, resistance and versatility.

Advantages as well as disadvantages of neodymium magnets NdFeB.

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

They retain their attractive force for around ten years – the drop is just ~1% (in theory),
They remain magnetized despite exposure to magnetic surroundings,
Thanks to the polished finish and silver coating, they have an visually attractive appearance,
They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
The ability for accurate shaping or adjustment to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
Significant impact in new technology industries – they find application in HDDs, electric drives, medical equipment as well as sophisticated instruments,
Compactness – despite their small size, they generate strong force, making them ideal for precision applications

Disadvantages of neodymium magnets:

They are fragile when subjected to a powerful impact. If the magnets are exposed to mechanical hits, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from cracks and reinforces its overall robustness,
They lose power at elevated temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing fine shapes directly in the magnet,
Health risk linked to microscopic shards may arise, if ingested accidentally, which is important in the health of young users. Additionally, miniature parts from these assemblies might interfere with diagnostics if inside the body,
Due to the price of neodymium, their cost is relatively high,

Caution with Neodymium Magnets

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 are highly susceptible to damage, leading to breaking.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.

Neodymium magnets can demagnetize at high temperatures.

Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.

The magnet is coated with nickel. Therefore, exercise caution 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.

Do not bring neodymium magnets close to GPS and smartphones.

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

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

Magnetic 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.

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 are the most powerful, most remarkable magnets on the planet, and the surprising force between them can surprise you at first.

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 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.

If have a finger between or on the path of attracting magnets, there may be a large cut or even a fracture.

Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.

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.

Warning!
