Magnetic properties of the material N38
Physical properties of sintered neodymium magnets Nd2Fe14B
Contact Surface: Thanks to their flat shape, disc magnets guarantee a larger contact surface with adjoining parts, which is beneficial in applications requiring a stronger magnetic connection.
Applications in Technology: They are often employed in many devices, such as sensors, stepper motors, or speakers, where a thin and wide shape is important for their operation.
Mounting: The flat form's flat shape facilitates mounting, particularly when you need to adhere the magnet to a surface.
Design Flexibility: The flat shape of the magnets gives designers with greater flexibility in placing them in constructions, which can sometimes be more difficult with magnets of other shapes.
Stability: In certain applications, the flat base of a disc magnet can provide better stability, minimizing the risk of shifting or rotating. Nevertheless, one should bear in mind that the optimal shape of a magnet is dependent on the specific application and requirements. In certain cases, other shapes, such as cylindrical or spherical, might be more suitable.

Advantages as well as disadvantages of neodymium magnets NdFeB.
Apart from 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 protect against demagnetization caused by external magnetic field extremely well,
- Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
- They exhibit very high magnetic induction on the surface of the magnet,
- Thanks to their high temperature resistance, they can operate (depending on the form) 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 amplifies their universality in usage.
- Significant importance in advanced technologically fields – are used in computer drives, electric motors, medical apparatus and various technologically advanced devices.
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 metal holder. The steel housing in the form of a holder protects the magnet from impacts and at the same time 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 - during 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 to health from tiny fragments of magnets can be dangerous, if swallowed, which becomes significant in the context of child safety. Furthermore, tiny parts of these magnets are able to complicate diagnosis after entering the body.
Caution with Neodymium Magnets
Keep neodymium magnets away from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
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 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.
Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can shock you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Do not bring neodymium magnets close to GPS and smartphones.
Magnetic fields can interfere with compasses and magnetometers used in aviation and maritime navigation, as well as internal compasses of smartphones and GPS devices. There are neodymium magnets in every smartphone, for example, in the microphone and speakers.
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. Small magnets can pose a serious choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing severe injuries, and even death.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Neodymium magnets bounce and also clash mutually within a radius of several to almost 10 cm from each other.
Neodymium magnetic are extremely delicate, they easily crack and can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. Despite being made of metal and coated with a shiny nickel plating, they are not as hard as steel. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
