Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Due to their strength, flat magnets are frequently used in structures that require very strong attraction.
Most common temperature resistance of flat magnets is 80°C, but with larger dimensions, this value grows.
In addition, flat magnets usually have special coatings applied to their surfaces, such as nickel, gold, or chrome, to improve their durability.
The magnet named MPL 200x30x30 / N38 and a lifting capacity of 183.51 kg weighing a mere 1350.00 grams, making it the ideal choice for projects needing a flat magnet.
Contact surface: Due to their flat shape, flat magnets guarantee a larger contact surface with other components, which can be beneficial in applications needing a stronger magnetic connection.
Technology applications: These magnets are often applied in various devices, e.g. sensors, stepper motors, or speakers, where the flat shape is important 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 gives the possibility designers a lot of 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. It’s important to keep in mind that the optimal shape of the magnet depends on the given use and requirements. In certain cases, other shapes, such as cylindrical or spherical, may be a better choice.
Magnets have two poles: north (N) and south (S), which attract each other when they are different. Similar poles, such as two north poles, act repelling on each other.
Due to these properties, magnets are regularly used in electrical devices, e.g. motors, speakers, sensors, or magnetic locks. Neodymium magnets stand out with the highest power of attraction, making them perfect for applications requiring powerful magnetic fields. Moreover, the strength of a magnet depends on its size and the material it is made of.
It’s worth noting 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. Additionally, strong magnets can interfere with the operation of devices, such as navigational instruments, magnetic stripe cards and even electronic devices sensitive to magnetic fields. For this reason, it is important to exercise caution when using magnets.

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 approximately 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field very well,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit extremely 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 form) 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 a wide range of shapes and sizes, which expands the range of their possible uses.
- Significant importance in the industry of new technologies – are utilized in hard drives, electric drive mechanisms, medical equipment and other advanced devices.
Disadvantages of neodymium magnets:
- They are prone to breaking as they are fragile when subjected to a strong impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also 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,
- The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
- Possible danger arising from small pieces of magnets are risky, when accidentally ingested, which is particularly important in the aspect of protecting young children. Furthermore, tiny parts of these magnets have the potential to complicate diagnosis in case of swallowing.
Exercise Caution with Neodymium Magnets
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are the most powerful magnets ever invented. Their strength can surprise you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
Neodymium magnets jump and clash mutually within a distance of several to almost 10 cm from each other.
Keep neodymium magnets away from TV, wallet, and computer HDD.
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. Avoid placing neodymium magnets in close proximity to electronic devices.
Magnets made of neodymium are highly fragile, they easily fall apart and can crumble.
Magnets made of neodymium are fragile 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. In the case of a collision between two magnets, there can be a scattering of small sharp metal fragments in different directions. Protecting your eyes is essential.
Keep neodymium magnets away from people with pacemakers.
In the case of neodymium magnets, there is a strong magnetic field. As a result, it interferes with the operation of a heart pacemaker. However, if the magnetic field does not affect the device, it can damage its components or deactivate the device when it is in a magnetic field.
The magnet coating is made of nickel, so be cautious 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets generate strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can demagnetize at high temperatures.
Even though magnets have been observed 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.
