Flat neodymium magnets min. MPL 40x15x5 / N38 are magnets made from neodymium in a rectangular form. They are appreciated for their exceptionally potent magnetic properties, which surpass ordinary ferrite magnets.
Due to their power, flat magnets are regularly applied in structures that require very strong attraction.
The standard temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value grows.
Moreover, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their strength.
The magnet labeled MPL 40x15x5 / N38 and a lifting capacity of 9.67 kg weighing just 22.5 grams, making it the perfect choice for applications requiring a flat shape.

Neodymium flat magnets provide a range of advantages compared to other magnet shapes, which make them being an ideal choice for a multitude of projects:
Contact surface: Due to their flat shape, flat magnets guarantee a greater contact surface with other components, which is beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often applied in different devices, e.g. sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: Their flat shape simplifies mounting, especially when there's a need to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets allows creators a lot of flexibility in arranging them in devices, which can be more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet can provide better stability, reducing the risk of shifting or rotating. However, it's important to note that the optimal shape of the magnet depends on the specific project and requirements. In certain cases, other shapes, like cylindrical or spherical, are more appropriate.

Attracted by magnets are ferromagnetic materials, such as iron elements, objects containing nickel, materials with cobalt and alloys of metals with magnetic properties. Moreover, magnets may weaker affect some other metals, 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 materials containing cobalt or other ferromagnetic substances.

Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, e.g. two north poles, act repelling on each other.
Due to these properties, magnets are regularly used in electrical devices, such as motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them indispensable for applications requiring strong magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the material it is made of.

Magnets do not attract plastics, glass, wooden materials and precious stones. Additionally, magnets do not affect certain metals, such as copper, aluminum materials, 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’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. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, magnetic stripe cards or 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 power, neodymium magnets have the following advantages:

They do not lose their strength (of the magnet). After approximately 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 exhibit extremely high magnetic induction on the surface of the magnet,
Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the shape) even at temperatures of 230°C or higher...
Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
Wide application in advanced technologically fields – are used in hard drives, electric drive mechanisms, medical equipment and very advanced devices.

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 steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously 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 loss in strength (although it is dependent on the form 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,
The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
Health risk associated with microscopic parts of magnets can be dangerous, in case of ingestion, which is crucial in the context of children's health. Additionally, small elements of these magnets have the potential to be problematic in medical diagnosis in case of swallowing.

Safety Guidelines with Neodymium Magnets

Neodymium magnets can become demagnetized at high temperatures.

While 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.

It is important to maintain neodymium magnets out of reach from children.

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.

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.

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.

Neodymium magnetic are delicate as well as can easily break as well as get damaged.

Neodymium magnets are characterized by significant fragility. 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, sharp metal fragments can be dispersed in different directions.

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.

It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.

Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to put fingers between magnets or in their path when they attract. Depending on how massive the neodymium magnets are, they can lead to a cut or a fracture.

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.

Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.

Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.

Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength can shock you.
