Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their power, flat magnets are frequently used in products that require very strong attraction.
The standard temperature resistance of flat magnets is 80 °C, but depending on the dimensions, this value can increase.
Moreover, flat magnets usually have different coatings applied to their surfaces, such as nickel, gold, or chrome, for enhancing their strength.
The magnet labeled MPL 10x4x1.5 / N38 i.e. a lifting capacity of 0.75 kg with a weight of only 0.45 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 other components, which can be beneficial in applications requiring a stronger magnetic connection.
Technology applications: These magnets are often utilized in many devices, such as sensors, stepper motors, or speakers, where the flat shape is important for their operation.
Mounting: The flat form's flat shape simplifies mounting, especially when it is required to attach the magnet to some surface.
Design flexibility: The flat shape of the magnets permits designers greater flexibility in placing them in devices, which can be more difficult with magnets of more complex shapes.
Stability: In certain applications, the flat base of the flat magnet can offer better stability, reducing the risk of sliding or rotating. It’s important to keep in mind that the optimal shape of the magnet is dependent on the given use and requirements. In certain cases, other shapes, like cylindrical or spherical, may be more appropriate.
Magnets have two main poles: north (N) and south (S), which attract each other when they are oppositely oriented. Similar poles, such as two north poles, repel each other.
Thanks to this principle of operation, 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 indispensable for applications requiring strong 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 under such conditions, the magnet stops being magnetic. Interestingly, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards and even medical equipment, like pacemakers. Therefore, it is important to avoid placing magnets near such devices.

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 have 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...
- 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.
- Wide application in modern technologies – are utilized in hard drives, electric drive mechanisms, medical apparatus and various technologically advanced devices.
Disadvantages of neodymium magnets:
- They can break as they are extremely fragile 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 simultaneously 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 loss 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 suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
- Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
- Potential hazard associated with microscopic parts of magnets pose a threat, when accidentally ingested, which is crucial in the context of children's health. Additionally, miniscule components of these magnets are able to be problematic in medical diagnosis after entering the body.
Exercise Caution with Neodymium Magnets
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If you have a finger between or alternatively on the path of attracting magnets, there may be a large cut or even a fracture.
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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
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.
Neodymium magnets are over 10 times more powerful than ferrite magnets (the ones in speakers), and their power can shock you.

Neodymium magnets should not be in the vicinity youngest children.
Remember that 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.
Neodymium magnetic are extremely fragile, they easily crack as well as can become damaged.
Neodymium magnets are extremely delicate, and by joining them in an uncontrolled manner, they will crumble. Magnets made of neodymium 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 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.
Keep neodymium magnets as far away as possible from 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 can become demagnetized at high temperatures.
Despite the fact that 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.
