Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They do not lose their strength around ten years – the decrease of power is only ~1% (based on measurements),
- They protect against demagnetization induced by surrounding magnetic fields effectively,
- The use of a polished gold surface provides a eye-catching finish,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- Neodymium magnets are known for very high magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the geometry),
- With the option for fine forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving application potential,
- Key role in new technology industries – they are used in data storage devices, electromechanical systems, medical equipment along with other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, with minimal size,
Disadvantages of rare earth magnets:
- They may fracture when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from breakage , and at the same time enhances its overall resistance,
- They lose field intensity at elevated temperatures. Most neodymium magnets experience permanent degradation in strength when heated above 80°C (depending on the shape 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 recommended to use sealed magnets made of protective material for outdoor use,
- Limited ability to create complex details in the magnet – the use of a magnetic holder is recommended,
- Potential hazard due to small fragments may arise, when consumed by mistake, which is notable in the family environments. Furthermore, miniature parts from these assemblies can hinder health screening once in the system,
- High unit cost – neodymium magnets are pricier than other types of magnets (e.g., ferrite), which can restrict large-scale applications
Exercise Caution with Neodymium Magnets
Neodymium magnets can become demagnetized 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.
Avoid contact with neodymium magnets 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, try wearing gloves or 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.
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. Even if the magnetic field does not affect the device, it can damage its components or deactivate the entire device.
Magnets made of neodymium are extremely fragile, resulting in shattering.
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. 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.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
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 damage devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.
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.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
Neodymium magnets will bounce and also touch together within a radius of several to around 10 cm from each other.
It is essential to keep neodymium magnets away from children.
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.
