Neodymium flat magnets min. MPL 60x10x5 / N38 are magnets created from neodymium in a rectangular form. They are valued for their exceptionally potent magnetic properties, which are much stronger than traditional ferrite magnets.
Due to their power, flat magnets are commonly used in devices that need strong holding power.
Most common temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value grows.
Additionally, flat magnets usually have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, to improve their strength.
The magnet with the designation MPL 60x10x5 / N38 and a magnetic force 9.67 kg weighing only 22.5 grams, making it the perfect choice for projects needing a flat magnet.

Neodymium flat magnets offer a range of advantages compared to other magnet shapes, which make them being the best choice for many applications:
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often applied in various devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: This form's flat shape makes it easier mounting, especially when it is necessary to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows designers a lot of flexibility in placing them in devices, which is more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of the flat magnet may provide better stability, reducing the risk of sliding or rotating. However, it's important to note that the optimal shape of the magnet is dependent on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, are more appropriate.

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

Magnets work thanks to the properties of their magnetic field, which arises from the ordered movement of electrons in their structure. Magnetic fields of magnets creates attractive forces, which affect objects made of cobalt or other ferromagnetic substances.

Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Similar poles, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are often used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.

Magnets do not attract plastics, glass items, wood and most gemstones. Additionally, magnets do not affect certain metals, such as copper items, aluminum, items made of gold. Although these metals conduct electricity, do not exhibit ferromagnetic properties, meaning that they do not respond to a standard magnetic field, unless they are subjected to an extremely 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 under such conditions, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards and even electronic devices sensitive to magnetic fields. Therefore, 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 their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
They are exceptionally resistant to demagnetization caused by an external magnetic field,
In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
They exhibit very 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...
The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
Significant importance in the industry of new technologies – are utilized in hard drives, electric drive mechanisms, medical devices and various technologically advanced devices.

Disadvantages of neodymium magnets:

They can break as they are extremely fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a metal holder. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
They lose power at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the form and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
Possible danger to health from tiny fragments of magnets are risky, when accidentally ingested, which is crucial in the context of child safety. Additionally, tiny parts of these devices can complicate diagnosis after entering the body.

Be Cautious with Neodymium Magnets

Neodymium magnets are the strongest magnets ever created, and their strength can shock you.

Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.

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

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 attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.

Neodymium magnets jump and clash mutually within a distance of several to around 10 cm from each other.

Neodymium magnets should not be near 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.

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

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.

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

Strong 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. Avoid placing neodymium magnets in close proximity to electronic devices.

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.

Keep neodymium magnets as far away as possible from GPS and smartphones.

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 are especially delicate, resulting in damage.

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