Flat neodymium magnets i.e. MPL 20x10x1 / N38 are magnets made from neodymium in a flat form. They are appreciated for their exceptionally potent magnetic properties, which outshine traditional ferrite magnets.
Thanks to their mighty power, flat magnets are regularly used in products that require strong holding power.
The standard temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value rises.
Moreover, flat magnets usually have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet labeled MPL 20x10x1 / N38 and a lifting capacity of 1.12 kg weighing a mere 1.5 grams, making it the excellent choice for projects needing a flat magnet.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which make them being the best choice for many applications:
Contact surface: Due to their flat shape, flat magnets ensure a greater contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, such as sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: This form's flat shape makes mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers a lot of flexibility in placing them in devices, which can be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, minimizing 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 some cases, other shapes, like cylindrical or spherical, are more appropriate.

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

Magnets work thanks to the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. Magnetic fields of these objects creates attractive forces, which attract objects made of iron or other magnetic materials.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are different. Poles of the same kind, such as two north poles, repel each other.
Due to these properties, magnets are regularly used in electrical devices, e.g. 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. Moreover, the strength of a magnet depends on its size and the material it is made of.

Magnets do not attract plastics, glass, wood and precious stones. Additionally, magnets do not affect most metals, such as copper items, aluminum materials, 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 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. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards or electronic devices sensitive to magnetic fields. For this reason, it is important to avoid placing magnets near such devices.

A neodymium magnet N52 and N50 is a strong and extremely powerful magnetic piece with the shape of a plate, that provides high force and universal application. Attractive price, 24h delivery, durability and multi-functionality.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their magnetic performance, neodymium magnets are valued for these benefits:

They have constant strength, and over more than ten years their attraction force decreases symbolically – ~1% (in testing),
They are highly resistant to demagnetization caused by external magnetic sources,
In other words, due to the shiny nickel coating, the magnet obtains an professional appearance,
They have extremely strong magnetic induction on the surface of the magnet,
Thanks to their exceptional temperature resistance, they can operate (depending on the geometry) even at temperatures up to 230°C or more,
With the option for fine forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
Wide application in modern technologies – they find application in hard drives, electromechanical systems, healthcare devices and high-tech tools,
Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them useful in small systems

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time reinforces its overall resistance,
They lose strength at extreme temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the geometry 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 recommended to use sealed magnets made of plastic for outdoor use,
Limited ability to create precision features in the magnet – the use of a magnetic holder is recommended,
Health risk due to small fragments may arise, especially if swallowed, which is significant in the protection of children. Furthermore, minuscule fragments from these products might disrupt scanning after being swallowed,
Due to a complex production process, their cost is relatively high,

Handle with Care: Neodymium Magnets

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

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

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

Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.

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.

Keep neodymium magnets away from people with pacemakers.

Neodymium magnets produce strong magnetic fields that can interfere 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.

It is important to maintain neodymium magnets out of reach from youngest 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 demagnetize at high temperatures.

Although magnets are generally resilient, 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.

Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.

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. You should especially avoid placing neodymium magnets near electronic devices.

Avoid contact with neodymium magnets 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.

Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.

Magnets attract each other within a distance of several to about 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 large the neodymium magnets are, they can lead to a cut or alternatively a fracture.

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

On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.

Exercise caution!
