Neodymium flat magnets min. MPL 6x6x6 / N38 are magnets made from neodymium in a flat form. They are appreciated for their extremely powerful magnetic properties, which surpass standard ferrite magnets.
Thanks to their mighty power, flat magnets are commonly applied in products that need very strong attraction.
Typical 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, such as nickel, gold, or chrome, to increase their corrosion resistance.
The magnet labeled MPL 6x6x6 / N38 i.e. a magnetic force 2.84 kg weighing a mere 1.62 grams, making it the ideal choice for applications requiring a flat shape.

Neodymium flat magnets offer a range of advantages versus other magnet shapes, which make them being a perfect solution for a multitude of projects:
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with adjacent parts, 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 important for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when it is required to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility creators a lot of flexibility in placing them in structures, which can be 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 depends on the specific application and requirements. In some cases, other shapes, such as cylindrical or spherical, are more appropriate.

Attracted by magnets are objects made of ferromagnetic materials, such as iron elements, objects containing nickel, materials with cobalt or special alloys of ferromagnetic metals. Moreover, magnets may lesser affect alloys containing iron, such as steel. Magnets are used in many fields.

The operation of magnets is based on the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. Magnetic fields of magnets creates attractive interactions, which affect 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 different. Poles of the same kind, e.g. two north poles, act repelling on 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 ideal for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its size and the materials used.

Magnets do not attract plastic, glass items, wood and most gemstones. Additionally, magnets do not affect certain metals, such as copper items, aluminum materials, 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 extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. 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, credit cards or electronic devices sensitive to magnetic fields. For this reason, it is important to exercise caution when using magnets.

Advantages and disadvantages of neodymium magnets NdFeB.

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

They do not lose strength over time - after about 10 years, their power decreases by only ~1% (theoretically),
They protect against demagnetization caused by external magnetic sources extremely well,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They have exceptionally high magnetic induction on the surface of the magnet,
Thanks to their high temperature resistance, they can operate (depending on the shape) even at temperatures up to 230°C and above...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
Significant importance in the industry of new technologies – are utilized in HDD drives, electric drive mechanisms, medical devices or various technologically advanced devices.

Disadvantages of neodymium magnets:

They can break as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Health risk arising from small pieces of magnets pose a threat, if swallowed, which is crucial in the context of child safety. Additionally, small elements of these products are able to be problematic in medical diagnosis after entering the body.

Handle with Care: Neodymium Magnets

Neodymium magnets can demagnetize at high temperatures.

Despite the fact that magnets have been observed to maintain their efficacy up to temperatures of 80°C or 175°F, it's essential to consider that this threshold may fluctuate depending on the magnet's type, configuration, and intended usage.

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

The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Magnets made of neodymium are delicate and can easily crack as well as shatter.

In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. 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.

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.

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.

The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.

Avoid bringing neodymium magnets close to a phone or GPS.

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.

Magnets should not be treated as toys. Therefore, it is not recommended for 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.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their power can surprise 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.

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

Magnets will attract each other within a distance of several to around 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how huge the neodymium magnets are, they can lead to a cut or a fracture.

Exercise caution!
