Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are commonly applied in devices that need exceptional adhesion.
Typical temperature resistance of flat magnets is 80°C, but depending on the dimensions, this value rises.
In addition, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their corrosion resistance.
The magnet labeled MPL 3x3x2 / N38 i.e. a magnetic force 0.47 kg weighing just 0.14 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets guarantee a greater contact surface with adjacent parts, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: They 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: The flat form's flat shape simplifies mounting, particularly when it is required 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 other shapes.
Stability: In certain applications, the flat base of the flat magnet can provide better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet depends on the specific application and requirements. In some cases, other shapes, like cylindrical or spherical, may be more appropriate.
Magnets have two 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 greatest strength of attraction, making them perfect 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 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. Interestingly, strong magnets can interfere with the operation of devices, such as compasses, credit cards or 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.
Apart from immense power, neodymium magnets have the following advantages:
- They do not lose power over time. After about 10 years, their strength decreases by only ~1% (theoretically),
- They are exceptionally resistant to demagnetization caused by an external magnetic field,
- In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
- They possess 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 and customization to specific needs – neodymium magnets can be produced in many variants of shapes and sizes, which enhances their versatility in applications.
- Key role in modern technologies – are utilized in computer drives, electric motors, medical apparatus and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful 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,
- High temperatures can reduce the strength of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction 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
- Potential hazard to health from tiny fragments of magnets are risky, if swallowed, which is particularly important in the aspect of protecting young children. Furthermore, small elements of these devices have the potential to be problematic in medical diagnosis in case of swallowing.
Handle Neodymium Magnets Carefully
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power 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 damage to the magnets.
The magnet is coated with nickel. Therefore, exercise caution 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnetic are extremely fragile, leading to breaking.
Magnets made of neodymium are extremely delicate, and by joining them in an uncontrolled manner, they will break. 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.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
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.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
If have a finger between or alternatively on the path of attracting magnets, there may be a severe cut or a fracture.
Do not place neodymium magnets 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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Dust and powder from neodymium magnets are flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets can demagnetize 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.
Neodymium magnets should not be in the vicinity 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.
