Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Thanks to their mighty power, flat magnets are regularly used in devices that need exceptional adhesion.
Most common temperature resistance of these magnets is 80°C, but depending on the dimensions, this value rises.
Additionally, flat magnets commonly have special coatings applied to their surfaces, e.g. nickel, gold, or chrome, for enhancing their durability.
The magnet labeled MPL 5x5x2 / N38 i.e. a magnetic force 0.79 kg weighing a mere 0.38 grams, making it the excellent choice for applications requiring a flat shape.
Contact surface: Due to their flat shape, flat magnets ensure a larger contact surface with other components, which is beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often used in different devices, such as sensors, stepper motors, or speakers, where the flat shape is crucial for their operation.
Mounting: This form's flat shape simplifies mounting, particularly when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets permits creators a lot of 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 offer better stability, reducing the risk of shifting or rotating. It’s important to keep in mind 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 interact with each other when they are different. Similar poles, e.g. two north poles, repel each other.
Due to these properties, magnets are commonly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the greatest strength of attraction, making them ideal for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its dimensions and the materials used.
It’s worth noting 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 navigational instruments, credit cards and even medical equipment, like pacemakers. Therefore, it is important to exercise caution when using magnets.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time. After 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 very 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 or the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which expands the range of their possible uses.
- Key role in the industry of new technologies – find application in computer drives, electric drive mechanisms, medical devices and very advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are fragile 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 also 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,
- Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- 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 pose a threat, if swallowed, which becomes significant in the context of children's health. It's also worth noting that small elements of these magnets have the potential to hinder the diagnostic process after entering the body.
Safety Precautions
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 on the path of attracting magnets, there may be a severe cut or even a fracture.
Neodymium magnets are extremely delicate, they easily break as well as can crumble.
Neodymium magnetic are delicate as well as will shatter if allowed to collide with each other, even from a distance of a few centimeters. Despite being made of metal as well as coated with a shiny nickel plating, they are not as hard as steel. At the moment of collision between the magnets, tiny sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional damage to the magnets.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Strong magnetic fields emitted by neodymium magnets can destroy magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
The magnet is coated with nickel - be careful if you have an allergy.
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.
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.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Never bring neodymium magnets close to a phone and GPS.
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.
Neodymium magnets should not be in the vicinity youngest 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.
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.
