Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are frequently applied in structures that need very strong attraction.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value can increase.
In addition, flat magnets often have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their durability.
The magnet labeled MPL 25x15x2 / N38 and a magnetic strength 3.06 kg weighing only 5.63 grams, making it the perfect choice for projects needing a flat magnet.
Contact surface: Due 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 magnets are often utilized in various devices, e.g. sensors, stepper motors, or speakers, where the thin and wide shape is crucial for their operation.
Mounting: This form's flat shape simplifies mounting, particularly 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 some applications, the flat base of the flat magnet can offer 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 project and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be a better choice.
Magnets have two main poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, repel each other.
Thanks to this principle of operation, magnets are regularly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them perfect for applications requiring strong magnetic fields. Additionally, the strength of a magnet depends on its dimensions and the materials used.
It should be noted that high temperatures can weaken the magnet's effect. Every magnetic material has its Curie point, meaning that under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards or medical equipment, like pacemakers. Therefore, 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 power (of the magnet). After about 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They have exceptionally 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...
- Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which amplifies their universality in usage.
- Significant importance in modern technologies – are utilized in hard drives, electric motors, medical equipment and other modern machines.
Disadvantages of neodymium magnets:
- They can break when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. The steel housing in the form of a holder protects the magnet from impacts, and at the same time 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,
- 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
- Possible danger arising from small pieces of magnets pose a threat, if swallowed, which is particularly important in the context of children's health. It's also worth noting that tiny parts of these devices are able to be problematic in medical diagnosis when they are in the body.
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from 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 magnets can become demagnetized at high temperatures.
Even though magnets have been found 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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Neodymium magnets are fragile and can easily break as well as shatter.
Magnets made of neodymium are fragile and will break if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
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.
If the joining of neodymium magnets is not controlled, at that time they may crumble and also crack. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
Keep neodymium magnets away from children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Never bring neodymium magnets close to a phone and GPS.
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 the most powerful magnets ever invented. Their power 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.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
So you are aware of why neodymium magnets are so dangerous, read the article titled How very dangerous are powerful neodymium magnets?.
