Flat neodymium magnets min. MPL 60x20x10 / N38 are magnets created from neodymium in a rectangular form. They are known for their very strong magnetic properties, which surpass ordinary ferrite magnets.
Thanks to their high strength, flat magnets are commonly applied in products that need exceptional adhesion.
The standard temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value can increase.
In addition, flat magnets often have different coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their corrosion resistance.
The magnet with the designation MPL 60x20x10 / N38 i.e. a magnetic strength 27.36 kg weighing a mere 90 grams, making it the perfect choice for projects needing a flat magnet.

Neodymium flat magnets provide a range of advantages compared to 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 guarantee a greater contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These are often applied in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: This form's flat shape makes it easier mounting, particularly when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in placing them in structures, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can offer better stability, reducing the risk of sliding or rotating. However, one should remember 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 more appropriate.

Attracted by magnets are ferromagnetic materials, such as iron elements, nickel, materials with cobalt and alloys of metals with magnetic properties. Additionally, magnets may lesser affect some other metals, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of the magnetic field, which is generated by the movement of electric charges within their material. The magnetic field of magnets creates attractive forces, 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, repel each other.
Due to these properties, magnets are commonly used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring powerful 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 items, wooden materials or precious stones. Furthermore, magnets do not affect certain metals, such as copper, aluminum, gold. These metals, although they are conductors of electricity, do not exhibit ferromagnetic properties, meaning that they remain unaffected by a magnet, unless they are subjected to an extremely 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. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards or medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

A neodymium plate magnet N50 and N52 is a powerful and strong metallic component with the shape of a plate, that provides high force and versatile application. Attractive price, fast shipping, stability and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

Besides their stability, neodymium magnets are valued for these benefits:

They do not lose their strength approximately 10 years – the loss of power is only ~1% (based on measurements),
They are very resistant to demagnetization caused by external field interference,
The use of a mirror-like gold surface provides a smooth finish,
They have very high magnetic induction on the surface of the magnet,
Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
With the option for customized forming and targeted design, these magnets can be produced in multiple shapes and sizes, greatly improving design adaptation,
Wide application in cutting-edge sectors – they are utilized in hard drives, electric motors, clinical machines along with sophisticated instruments,
Thanks to their efficiency per volume, small magnets offer high magnetic performance, with minimal size,

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 at the same time increases its overall resistance,
Magnets lose power when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible magnetic decay (influenced by the magnet’s profile). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a damp environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of polymer,
The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
Potential hazard related to magnet particles may arise, when consumed by mistake, which is important in the protection of children. Moreover, miniature parts from these magnets have the potential to complicate medical imaging when ingested,
In cases of large-volume purchasing, neodymium magnet cost is a challenge,

Breakaway strength of the magnet in ideal conditions – what affects it?

The given holding capacity of the magnet corresponds to the highest holding force, assessed in ideal conditions, specifically:

with mild steel, serving as a magnetic flux conductor
with a thickness of minimum 10 mm
with a smooth surface
in conditions of no clearance
in a perpendicular direction of force
in normal thermal conditions

Magnet lifting force in use – key factors

The lifting capacity of a magnet is influenced by in practice key elements, according to their importance:

Air gap between the magnet and the plate, as even a very small distance (e.g. 0.5 mm) can cause a drop in lifting force of up to 50%.
Direction of applied force, because the maximum lifting capacity is achieved under perpendicular application. The force required to slide the magnet along the plate is usually several times lower.
Thickness of the plate, as a plate that is too thin causes part of the magnetic flux not to be used and to remain wasted in the air.
Material of the plate, because higher carbon content lowers holding force, while higher iron content increases it. The best choice is steel with high magnetic permeability and high saturation induction.
Surface of the plate, because the more smooth and polished it is, the better the contact and consequently the greater the magnetic saturation.
Operating temperature, since all permanent magnets have a negative temperature coefficient. This means that at high temperatures they are weaker, while at sub-zero temperatures they become slightly stronger.

* Lifting capacity testing was conducted on a smooth plate of optimal thickness, under perpendicular forces, however under shearing force the lifting capacity is smaller. Moreover, even a minimal clearance {between} the magnet’s surface and the plate lowers the holding force.

Precautions with Neodymium Magnets

Never bring neodymium magnets close to a phone and GPS.

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

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

Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when attract. Magnets, depending on their size, are able even cut off a finger or there can be a significant pressure or even a fracture.

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

Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.

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

Magnets made of neodymium are delicate as well as 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.

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

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. Remember not to place neodymium magnets close to these electronic devices.

Dust and powder from neodymium magnets are highly 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.

Neodymium magnets can become demagnetized at high temperatures.

In certain circumstances, Neodymium magnets may experience demagnetization when subjected to high temperatures.

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.

Avoid contact with neodymium magnets 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.

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

Remember that neodymium magnets are not toys. Do not allow children to play 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.
