Neodymium flat magnets min. MPL 6x6x6 / N38 are magnets created from neodymium in a flat form. They are valued for their exceptionally potent magnetic properties, which are much stronger than ordinary ferrite magnets.
Thanks to their mighty power, flat magnets are regularly applied in structures that need exceptional adhesion.
The standard temperature resistance of these magnets is 80 °C, but with larger dimensions, this value rises.
Moreover, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their corrosion resistance.
The magnet labeled MPL 6x6x6 / N38 i.e. a lifting capacity of 2.84 kg weighing a mere 1.62 grams, making it the excellent choice for applications requiring a flat shape.

Neodymium flat magnets offer a range of advantages versus other magnet shapes, which make them being an ideal choice for many applications:
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often used in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: Their flat shape makes it easier mounting, particularly when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets gives the possibility designers a lot of flexibility in placing them in structures, which is 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 shifting or rotating. However, it's important to note that the optimal shape of the magnet depends on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, are more appropriate.

Attracted by magnets are objects made of ferromagnetic materials, such as iron, nickel, cobalt and alloys of metals with magnetic properties. 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 forces, which attract objects made of cobalt or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which attract each other when they are oppositely oriented. Poles of the same kind, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are commonly used in magnetic technologies, 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 dimensions and the materials used.

Magnets do not attract plastics, glass, wooden materials or most gemstones. Additionally, magnets do not affect most metals, such as copper items, aluminum, 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 should be noted that extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. Every magnetic material has its Curie point, meaning that once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as compasses, credit cards or medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

A flat magnet with classification N50 and N52 is a strong and powerful metallic component shaped like a plate, providing strong holding power and universal applicability. Competitive price, 24h delivery, ruggedness and multi-functionality.

Advantages and disadvantages of neodymium magnets NdFeB.

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

Their power remains stable, and after approximately 10 years, it drops only by ~1% (according to research),
They are very resistant to demagnetization caused by external magnetic sources,
By applying a shiny layer of nickel, the element gains a clean look,
They have exceptional magnetic induction on the surface of the magnet,
These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to form),
With the option for tailored forming and precise design, these magnets can be produced in multiple shapes and sizes, greatly improving engineering flexibility,
Wide application in advanced technical fields – they find application in computer drives, electric drives, diagnostic apparatus or even technologically developed systems,
Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications

Disadvantages of magnetic elements:

They can break when subjected to a sudden impact. If the magnets are exposed to mechanical hits, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time increases its overall robustness,
They lose magnetic force at elevated temperatures. Most neodymium magnets experience permanent reduction 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 advisable to use sealed magnets made of plastic for outdoor use,
Limited ability to create precision features in the magnet – the use of a housing is recommended,
Safety concern linked to microscopic shards may arise, if ingested accidentally, which is important in the context of child safety. It should also be noted that miniature parts from these devices may complicate medical imaging if inside the body,
Due to the price of neodymium, their cost is above average,

Handle Neodymium Magnets with Caution

Never bring neodymium magnets close to a phone and GPS.

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.

Neodymium magnets should not be near 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.

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

If the joining of neodymium magnets is not under control, then they may crumble and crack. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.

Magnets made of neodymium are especially delicate, which leads to damage.

Magnets made of neodymium are highly delicate, and by joining them in an uncontrolled manner, they will break. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.

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.

Maintain neodymium magnets away from children.

Remember that 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.

The magnet coating contains nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Neodymium magnets can become demagnetized at high temperatures.

Whilst Neodymium magnets can demagnetize 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.

Neodymium magnets are the strongest magnets ever invented. Their power 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 damage to the magnets.

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.

Be careful!
