Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are frequently used in structures that need very strong attraction.
The standard temperature resistance of these magnets is 80 °C, but depending on the dimensions, this value can increase.
Moreover, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, to increase their corrosion resistance.
The magnet with the designation MPL 10x7x3 / N38 and a magnetic force 1.98 kg with a weight of only 1.58 grams, making it the perfect 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 requiring a stronger magnetic connection.
Technology applications: These are often utilized 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, especially when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in placing them in devices, which is more difficult with magnets of more complex shapes.
Stability: In some applications, the flat base of the flat magnet may provide better stability, minimizing the risk of sliding or rotating. However, one should remember that the optimal shape of the magnet depends on the specific project 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 interact with each other when they are different. Poles of the same kind, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are often 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 size and the material it is made of.
It should be noted that high temperatures can weaken the magnet's effect. 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 compasses, magnetic stripe cards and even electronic devices sensitive to magnetic fields. Therefore, it is important to exercise caution when using magnets.

Advantages as well as 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 approximately 10 years, their strength decreases by only ~1% (theoretically),
- They are highly resistant to demagnetization by external magnetic sources,
- By applying a shiny coating of nickel, gold, or silver, the element gains 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 form) even at temperatures up to 230°C and above...
- Thanks to the flexibility in shaping or the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which expands the range of their possible uses.
- Key role in modern technologies – find application in hard drives, electric motors, medical apparatus and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are extremely fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
- They lose strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- 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
- Potential hazard to health from tiny fragments of magnets are risky, in case of ingestion, which is crucial in the aspect of protecting young children. Additionally, small elements of these products have the potential to complicate diagnosis in case of swallowing.
Handle Neodymium Magnets Carefully
Neodymium magnets are the strongest, most remarkable magnets on the planet, and the surprising force between them can shock you at first.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional damage to the magnets.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
Magnets may crack or alternatively crumble with uncontrolled connecting to each other. You can't approach them to each other. At a distance less than 10 cm you should hold them extremely strongly.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
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, or other 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 fragile as well as can easily crack and shatter.
Neodymium magnets are characterized by significant fragility. 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.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties 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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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.
Magnets are not toys, youngest should not play with 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.
Keep neodymium magnets away from GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
The magnet is coated with nickel - be careful 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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
In order for you to know how powerful neodymium magnets are and why they are so dangerous, see the article - Dangerous powerful neodymium magnets.
