Magnetic properties of the material N42
Physical properties of sintered neodymium magnets Nd2Fe14B
Compilation of suggested goods
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to immense strength, neodymium magnets have the following advantages:
- They do not lose strength over time - after 10 years, their power decreases by only ~1% (theoretically),
- They protect against demagnetization caused by external magnetic field extremely well,
- In other words, thanks to the shiny nickel, gold, or silver finish, 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...
- The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
- Significant importance in modern technologies – are used in hard drives, electric motors, medical devices or very 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 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 strength at high temperatures. Most neodymium magnets experience permanent loss of strength when heated above 80°C (depending on the shape and height). However, we also offer special magnets with high temperature resistance, up to 230°C,
- 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 to health from tiny fragments of magnets can be dangerous, in case of ingestion, which becomes significant in the context of child safety. Additionally, tiny parts of these devices have the potential to hinder the diagnostic process in case of swallowing.
Precautions
It is important to keep neodymium magnets out of reach from 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.
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.
Keep neodymium magnets away from GPS and smartphones.
Neodymium magnets produce strong magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets are the strongest, most remarkable magnets on earth, and the surprising force between them can shock you at first.
Read the information on our website on how to properly utilize neodymium magnets and avoid significant harm to your body and unintentional disruption to the magnets.
The magnet is coated with nickel. Therefore, exercise caution 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 become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
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.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Neodymium magnets produce strong 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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Magnets made of neodymium are especially delicate, which leads to their breakage.
Neodymium magnets are characterized by considerable fragility. 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, sharp metal fragments can be dispersed in different directions.
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.
Magnets attract each other within a distance of several to around 10 cm from each other. Remember not to insert fingers between magnets or alternatively in their path when they attract. Magnets, depending on their size, are able even cut off a finger or alternatively there can be a severe pressure or a fracture.
