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 require very strong attraction.
Typical temperature resistance of flat magnets is 80 °C, but with larger dimensions, this value can increase.
In addition, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to increase their strength.
The magnet labeled MPL 15x2x30 / N38 i.e. a lifting capacity of 2.73 kg weighing a mere 6.75 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Thanks to their flat shape, flat magnets ensure a larger contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These are often used in many devices, such as sensors, stepper motors, or speakers, where the thin and wide shape is important for their operation.
Mounting: This form's flat shape makes it easier mounting, particularly when there's a need to attach the magnet to another surface.
Design flexibility: The flat shape of the magnets gives the possibility designers greater flexibility in arranging 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 offer better stability, reducing the risk of shifting or rotating. However, one should remember that the optimal shape of the magnet depends on the specific project and requirements. In some cases, other shapes, such as cylindrical or spherical, may be more appropriate.
Magnets have two main poles: north (N) and south (S), which interact with each other when they are oppositely oriented. Similar poles, e.g. two north poles, repel each other.
Thanks to this principle of operation, magnets are commonly used in magnetic technologies, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them ideal 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 extremely high temperatures, above the Curie point, cause a loss of magnetic properties in the magnet. 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, 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 strength, neodymium magnets have the following advantages:
- They do not lose power over time. After about 10 years, their power 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 very high magnetic induction on the surface of the magnet,
- Magnetic neodymium magnets are characterized by very 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 a wide range of shapes and sizes, which amplifies their universality in usage.
- Significant importance in modern technologies – find application in hard drives, electric motors, medical equipment and other modern machines.
Disadvantages of neodymium magnets:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. 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 power 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,
- 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, when accidentally ingested, which is crucial in the aspect of protecting young children. Furthermore, tiny parts of these devices can be problematic in medical diagnosis after entering the body.
Precautions
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.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to maintain their magnetic potency can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
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 have them extremely strongly.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets generate intense magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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 are extremely fragile, leading to their cracking.
Neodymium magnetic 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, small metal fragments can be dispersed in different directions.
Magnets are not toys, youngest should not play with them.
Neodymium magnets are not toys. Do not allow children to play 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 magnets are the strongest magnets ever created, and their power can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent disruption to the magnets.
