Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their high strength, flat magnets are commonly applied in devices that need exceptional adhesion.
The standard temperature resistance of these magnets is 80°C, but with larger dimensions, this value grows.
In addition, flat magnets often have different coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their corrosion resistance.
The magnet with the designation MPL 5x5x2 / N38 i.e. a magnetic strength 0.79 kg with a weight of only 0.38 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Thanks to their flat shape, flat magnets ensure a greater contact surface with adjacent parts, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often used in many devices, e.g. sensors, stepper motors, or speakers, where the flat shape is necessary for their operation.
Mounting: This form's flat shape simplifies mounting, especially when it is necessary to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in placing them in devices, 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 specific application and requirements. In certain cases, other shapes, like cylindrical or spherical, are a better choice.
Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Poles of the same kind, e.g. two north poles, repel each other.
Due to these properties, magnets are commonly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power 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.
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 once this temperature is exceeded, the magnet stops being magnetic. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, credit cards and even medical equipment, like pacemakers. For this reason, it is important to exercise caution when using magnets.

Advantages as well as 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 about 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit extremely high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very high magnetic induction on the surface of the magnet and can operate (depending on the form) 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 many variants of shapes and sizes, which expands the range of their possible uses.
- Wide application in advanced technologically fields – find application in hard drives, electric drive mechanisms, medical apparatus or various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a strong 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 at the same time increases its overall strength,
- Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent reduction in strength (although it is worth noting that this is dependent on the shape and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
- They rust in a humid environment - during outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
- 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
- Potential hazard associated with microscopic parts of magnets can be dangerous, if swallowed, which is crucial in the context of children's health. Additionally, small elements of these products can hinder the diagnostic process when they are in the body.
Be Cautious with Neodymium Magnets
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise you.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Magnets will attract each other within a distance of several to about 10 cm from each other. Remember not to insert fingers between magnets or in their path when they attract. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a serious pressure or a fracture.
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.
Do not place neodymium magnets 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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
Neodymium magnets can demagnetize at high temperatures.
Despite the general resilience of magnets, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Do not give neodymium magnets to youngest children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
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.
Neodymium magnets are not recommended for people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes 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 magnets are characterized by being fragile, which can cause them to shatter.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
