Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their tremendous strength, neodymium magnets offer the following advantages:
- They have constant strength, and over around 10 years their performance decreases symbolically – ~1% (according to theory),
- They are extremely resistant to demagnetization caused by external field interference,
- Thanks to the shiny finish and silver coating, they have an aesthetic appearance,
- They have very high magnetic induction on the surface of the magnet,
- With the right combination of compounds, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the design),
- The ability for accurate shaping and adaptation to custom needs – neodymium magnets can be manufactured in a wide range of shapes and sizes, which amplifies their functionality across industries,
- Key role in advanced technical fields – they are utilized in computer drives, electric motors, clinical machines or even other advanced devices,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of NdFeB magnets:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to shocks, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks while also reinforces its overall durability,
- They lose magnetic force at high temperatures. Most neodymium magnets experience permanent decline in strength when heated above 80°C (depending on the geometry and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- Magnets exposed to moisture can degrade. Therefore, for outdoor applications, we recommend waterproof types made of coated materials,
- Limited ability to create precision features in the magnet – the use of a housing is recommended,
- Health risk due to small fragments may arise, in case of ingestion, which is crucial in the context of child safety. Moreover, small elements from these assemblies can interfere with diagnostics when ingested,
- Due to a complex production process, their cost is above average,
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from TV, wallet, and computer HDD.
Strong magnetic fields emitted by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other devices. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock you.
Familiarize yourself with our information to properly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
Magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can attract to each other, pinch the skin, and cause significant injuries.
If joining of neodymium magnets is not controlled, at that time they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should hold them very firmly.
Neodymium magnets should not be around youngest children.
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 significant injuries, and even death.
Magnets made of neodymium are highly delicate, they easily break and can become damaged.
Magnets made of neodymium are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets produce strong magnetic fields that can interfere 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.
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.
The magnet coating is made of nickel, so be cautious 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.
