Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their magnetic efficiency, neodymium magnets provide the following advantages:
- They virtually do not lose strength, because even after 10 years, the decline in efficiency is only ~1% (according to literature),
- They protect against demagnetization induced by ambient magnetic influence effectively,
- Thanks to the glossy finish and silver coating, they have an elegant appearance,
- The outer field strength of the magnet shows elevated magnetic properties,
- These magnets tolerate extreme temperatures, often exceeding 230°C, when properly designed (in relation to form),
- Thanks to the freedom in shaping and the capability to adapt to specific requirements, neodymium magnets can be created in various configurations, which broadens their application range,
- Important function in modern technologies – they are utilized in computer drives, electric motors, medical equipment and technologically developed systems,
- Thanks to their power density, small magnets offer high magnetic performance, in miniature format,
Disadvantages of NdFeB magnets:
- They are fragile when subjected to a sudden impact. If the magnets are exposed to external force, we recommend in a protective case. The steel housing, in the form of a holder, protects the magnet from fracture and reinforces its overall resistance,
- They lose power at elevated temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the form and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of protective material for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing complex structures directly in the magnet,
- Potential hazard due to small fragments may arise, especially if swallowed, which is significant in the family environments. Additionally, minuscule fragments from these assemblies can hinder health screening after being swallowed,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Safety Precautions
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets may crack or 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 very strongly.
Neodymium magnets can become demagnetized at high temperatures.
Even though 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.
Dust and powder from neodymium magnets are 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.
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Neodymium magnets are highly susceptible to damage, resulting in their cracking.
Neodymium magnets are characterized by significant fragility. Neodymium magnetic are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
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 happens because such devices have a function to deactivate them in a magnetic field.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets produce strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets at a safe distance from these electronic devices.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are among the strongest magnets on Earth. The surprising force they generate between each other can surprise 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.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
