Neodymium flat magnets min. MPL 10x5x1.5 / N38 are magnets created from neodymium in a flat form. They are appreciated for their very strong magnetic properties, which are much stronger than traditional ferrite magnets.
Due to their power, flat magnets are frequently applied in products that need very strong attraction.
Most common temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value grows.
Additionally, flat magnets commonly have special coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet with the designation MPL 10x5x1.5 / N38 and a magnetic force 0.84 kg weighing just 0.56 grams, making it the perfect choice for applications requiring a flat shape.

Neodymium flat magnets present a range of advantages versus other magnet shapes, which make them being a perfect solution for many applications:
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: They are often used in different devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: Their flat shape makes mounting, especially when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits creators 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 may offer better stability, reducing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet is dependent on the given use and requirements. In some cases, other shapes, like cylindrical or spherical, may be a better choice.

Magnets attract ferromagnetic materials, such as iron elements, objects containing nickel, cobalt and special alloys of ferromagnetic metals. Moreover, magnets may lesser 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 the magnetic field, which is generated by the movement of electric charges within their material. Magnetic fields of magnets creates attractive interactions, which affect objects made of cobalt or other magnetic materials.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Similar poles, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are regularly used in magnetic technologies, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring powerful magnetic fields. Additionally, the strength of a magnet depends on its size and the material it is made of.

Not all materials react to magnets, and examples of such substances are plastic, glass, wood or most gemstones. Additionally, magnets do not affect certain metals, such as copper, aluminum materials, items made of gold. Although these metals conduct 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. 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 navigational instruments, magnetic stripe cards and even medical equipment, like pacemakers. For this reason, it is important to avoid placing magnets near such devices.

Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

They do not lose power over time - after approximately 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic field very well,
In other words, thanks to the shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
They have exceptionally high magnetic induction on the surface of the magnet,
By using an appropriate combination of materials, they can achieve significant thermal resistance, allowing them to operate at temperatures up to 230°C and above...
Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
Significant importance in the industry of new technologies – are used in computer drives, electric motors, medical equipment or very highly developed apparatuses.

Disadvantages of neodymium magnets:

They are prone to breaking as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
Due to their susceptibility to corrosion in a humid environment, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
Possible danger arising from small pieces of magnets can be dangerous, when accidentally ingested, which is particularly important in the aspect of protecting young children. Additionally, small elements of these products are able to hinder the diagnostic process in case of swallowing.

Be Cautious with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.

The magnet coating is made of nickel, so be cautious 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.

Magnets are not toys, children should not play with them.

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.

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

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

Neodymium magnets are characterized by their fragility, which can cause them to 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. 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.

Do not bring neodymium magnets close to GPS and smartphones.

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.

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

To use magnets properly, it is best to familiarize yourself with our information beforehand. This will help you avoid significant harm to your body and the magnets themselves.

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 bounce and contact together within a radius of several to around 10 cm from each other.

Dust and powder from neodymium magnets are flammable.

Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it 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. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.

Exercise caution!
