Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their magnetic capacity, neodymium magnets provide the following advantages:
- Their strength remains stable, and after approximately 10 years, it drops only by ~1% (according to research),
- They show superior resistance to demagnetization from external field exposure,
- The use of a decorative nickel surface provides a eye-catching finish,
- 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 flexibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which increases their usage potential,
- Significant impact in advanced technical fields – they find application in data storage devices, rotating machines, medical equipment as well as sophisticated instruments,
- Relatively small size with high magnetic force – neodymium magnets offer impressive pulling strength in small dimensions, which allows for use in small systems
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to external force, 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 reinforces its overall durability,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent decline in performance (depending on height). To prevent this, we offer heat-resistant magnets marked [AH], capable of working up to 230°C, which makes them perfect for high-temperature use,
- Due to corrosion risk in humid conditions, it is wise to use sealed magnets made of rubber for outdoor use,
- Limited ability to create precision features in the magnet – the use of a housing is recommended,
- Safety concern from tiny pieces may arise, in case of ingestion, which is important in the health of young users. Moreover, minuscule fragments from these devices may complicate medical imaging when ingested,
- Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications
Caution with Neodymium Magnets
Neodymium magnets can become demagnetized at high temperatures.
Although magnets have demonstrated their effectiveness up to 80°C or 175°F, the temperature can vary depending on the type, shape, and intended use of the specific magnet.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
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.
Magnets will crack or alternatively crumble with uncontrolled joining to each other. Remember not to approach them to each other or hold them firmly in hands at a distance less than 10 cm.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
Magnets should not be treated as toys. Therefore, it is not recommended for children to have access to them.
Remember that 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.
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.
Neodymium magnets are the strongest magnets ever created, and their power can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.
Neodymium magnets are highly fragile, they easily fall apart as well as can become damaged.
Neodymium magnets are fragile as well as will break if allowed to collide with each other, even from a distance of a few centimeters. 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.
Keep neodymium magnets away from the wallet, computer, and TV.
Neodymium magnets produce strong 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 destroy videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Avoid bringing neodymium magnets close to a phone or GPS.
Magnetic fields interfere with compasses and magnetometers used in navigation for air and sea transport, as well as internal compasses of smartphones and GPS devices.
Be careful!
