Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable field intensity, neodymium magnets offer the following advantages:
- They have stable power, and over nearly ten years their attraction force decreases symbolically – ~1% (in testing),
- They protect against demagnetization induced by ambient magnetic influence very well,
- By applying a reflective layer of silver, the element gains a modern look,
- They exhibit elevated levels of magnetic induction near the outer area of the magnet,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
- Thanks to the freedom in shaping and the capability to adapt to individual requirements, neodymium magnets can be created in different geometries, which expands their application range,
- Important function in cutting-edge sectors – they serve a purpose in computer drives, electromechanical systems, healthcare devices or even sophisticated instruments,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which allows for use in small systems
Disadvantages of rare earth 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 fracture and additionally reinforces its overall resistance,
- They lose magnetic force at increased temperatures. Most neodymium magnets experience permanent loss 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,
- Magnets exposed to moisture can oxidize. Therefore, for outdoor applications, we recommend waterproof types made of plastic,
- Using a cover – such as a magnetic holder – is advised due to the limitations in manufacturing fine shapes directly in the magnet,
- Health risk linked to microscopic shards may arise, if ingested accidentally, which is significant in the health of young users. Moreover, small elements from these devices may interfere with diagnostics 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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
Magnets attract each other within a distance of several to about 10 cm from each other. Don't put your fingers in the path of magnet attraction, because a serious injury may occur. Depending on how huge the neodymium magnets are, they can lead to a cut or alternatively a fracture.
Dust and powder from neodymium magnets are highly 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 made of neodymium are incredibly delicate, they easily break as well as can become damaged.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of collision between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets should not be around youngest children.
Remember that 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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
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.
Neodymium magnets are not recommended for people with pacemakers.
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.
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.
