Flat neodymium magnets min. MPL 5x5x1.2 / N38 are magnets made from neodymium in a rectangular form. They are appreciated for their very strong magnetic properties, which outshine traditional ferrite magnets.
Thanks to their mighty power, flat magnets are commonly applied in products that require exceptional adhesion.
Typical temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value rises.
Additionally, flat magnets usually have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet with the designation MPL 5x5x1.2 / N38 i.e. a magnetic strength 0.47 kg which weighs a mere 0.23 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets present a range of advantages compared to other magnet shapes, which lead to them being an ideal choice for various uses:
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These are often applied in different devices, such as sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: Their flat shape makes mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers a lot of flexibility in arranging them in structures, which is more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet can offer better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, may be a better choice.

Magnets attract ferromagnetic materials, such as iron elements, nickel, materials with cobalt or alloys of metals with magnetic properties. Moreover, magnets may weaker affect alloys containing iron, 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. Magnetic fields of magnets creates attractive interactions, which attract objects made of cobalt or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are commonly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them indispensable 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, wooden materials and most gemstones. Additionally, magnets do not affect most 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 exposed to a very strong magnetic field.
It’s worth noting that high temperatures can weaken the magnet's effect. 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 navigational instruments, magnetic stripe cards or medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

A neodymium plate magnet N50 and N52 is a strong and extremely powerful magnetic product with the shape of a plate, featuring high force and broad usability. Competitive price, 24h delivery, ruggedness and universal usability.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to their pulling strength, neodymium magnets provide the following advantages:

They retain their full power for around 10 years – the loss is just ~1% (based on simulations),
They show exceptional resistance to demagnetization from external magnetic fields,
The use of a mirror-like nickel surface provides a smooth finish,
They have very high magnetic induction on the surface of the magnet,
Thanks to their enhanced temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C or more,
The ability for precise shaping as well as adjustment to custom needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
Wide application in new technology industries – they are utilized in HDDs, electric motors, clinical machines as well as technologically developed systems,
Thanks to their power density, small magnets offer high magnetic performance, in miniature format,

Disadvantages of neodymium magnets:

They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is advisable to use in a protective case. The steel housing, in the form of a holder, protects the magnet from damage and additionally reinforces its overall robustness,
Magnets lose field strength when exposed to temperatures exceeding 80°C. In most cases, this leads to irreversible performance loss (influenced by the magnet’s structure). To address this, we provide [AH] models with superior thermal resistance, able to operate even at 230°C or more,
They rust in a wet environment. If exposed to rain, we recommend using encapsulated magnets, such as those made of rubber,
Limited ability to create complex details in the magnet – the use of a housing is recommended,
Potential hazard due to small fragments may arise, in case of ingestion, which is crucial in the protection of children. It should also be noted that miniature parts from these devices can complicate medical imaging once in the system,
In cases of tight budgets, neodymium magnet cost may be a barrier,

Maximum lifting capacity of the magnet – what affects it?

The given strength of the magnet represents the optimal strength, determined in ideal conditions, that is:

using a steel plate with low carbon content, acting as a magnetic circuit closure
of a thickness of at least 10 mm
with a polished side
with no separation
under perpendicular detachment force
at room temperature

Lifting capacity in practice – influencing factors

Practical lifting force is determined by elements, by priority:

Air gap between the magnet and the plate, since 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 was measured using a steel plate with a smooth surface of optimal thickness (min. 20 mm), under perpendicular pulling force, however under shearing force the load capacity is reduced by as much as 75%. Additionally, even a minimal clearance {between} the magnet’s surface and the plate decreases the lifting capacity.

We Recommend Caution with Neodymium Magnets

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.

Under no circumstances should neodymium magnets be brought close to GPS and smartphones.

Neodymium magnets produce intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.

Neodymium magnets are not recommended for people with pacemakers.

Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.

If you have a nickel allergy, avoid contact with neodymium magnets.

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, 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 youngest children to have access to them.

Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.

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

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.

You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.

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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.

Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.

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

Magnets made of neodymium are delicate and can easily crack and get damaged.

Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.

Exercise caution!
