Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their remarkable magnetic power, neodymium magnets offer the following advantages:
- Their power is durable, and after approximately ten years, it drops only by ~1% (theoretically),
- They are highly resistant to demagnetization caused by external magnetic sources,
- Because of the reflective layer of nickel, the component looks high-end,
- They possess intense magnetic force measurable at the magnet’s surface,
- They are suitable for high-temperature applications, operating effectively at 230°C+ due to advanced heat resistance and form-specific properties,
- Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in various configurations, which increases their application range,
- Key role in advanced technical fields – they find application in data storage devices, electric motors, diagnostic apparatus and high-tech tools,
- Thanks to their power density, small magnets offer high magnetic performance, with minimal size,
Disadvantages of neodymium magnets:
- They are prone to breaking when subjected to a sudden impact. If the magnets are exposed to mechanical hits, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks , and at the same time strengthens its overall durability,
- They lose field intensity at extreme temperatures. Most neodymium magnets experience permanent loss 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 wise to use sealed magnets made of plastic for outdoor use,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is not feasible,
- Health risk linked to microscopic shards may arise, especially if swallowed, which is notable in the protection of children. It should also be noted that small elements from these devices might hinder health screening if inside the body,
- High unit cost – neodymium magnets are more expensive than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Exercise Caution with Neodymium Magnets
Keep neodymium magnets away from youngest children.
Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Under no circumstances should neodymium magnets be brought close to GPS and smartphones.
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 demagnetize at high temperatures.
Under specific conditions, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Magnets made of neodymium are extremely fragile, resulting in shattering.
Neodymium magnetic are fragile and 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. At the moment of collision between the magnets, tiny sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium magnets are the strongest magnets ever invented. Their power can shock 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.
Keep neodymium magnets away from the wallet, computer, and TV.
Strong fields generated by neodymium magnets can damage magnetic storage media such as floppy disks, credit cards, magnetic ID cards, cassette tapes, video tapes, or other similar devices. They can also damage televisions, VCRs, computer monitors, and CRT displays. Avoid placing neodymium magnets in close proximity to electronic devices.
People with pacemakers are advised to avoid neodymium magnets.
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.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
If joining of neodymium magnets is not controlled, at that time they may crumble and crack. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
Pay attention!
