Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their immense magnetic power, neodymium magnets offer the following advantages:
- Their power remains stable, and after approximately 10 years, it drops only by ~1% (according to research),
- They show exceptional resistance to demagnetization from external magnetic fields,
- Thanks to the glossy finish and gold coating, they have an aesthetic appearance,
- Magnetic induction on the surface of these magnets is very strong,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to form),
- The ability for accurate shaping and adaptation to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Important function in cutting-edge sectors – they find application in HDDs, electric motors, diagnostic apparatus and other advanced devices,
- Thanks to their efficiency per volume, small magnets offer high magnetic performance, in miniature format,
Disadvantages of magnetic elements:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to physical collisions, they should be placed in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture while also enhances its overall durability,
- They lose field intensity at high temperatures. Most neodymium magnets experience permanent loss 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,
- Due to corrosion risk in humid conditions, it is common to use sealed magnets made of protective material for outdoor use,
- Limited ability to create threads in the magnet – the use of a external casing is recommended,
- Safety concern from tiny pieces may arise, especially if swallowed, which is important in the context of child safety. Furthermore, tiny components from these products may disrupt scanning 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
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.
Magnets made of neodymium are extremely fragile, leading to their cracking.
Magnets made of neodymium are extremely fragile, and by joining them in an uncontrolled manner, they will crack. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. In the event of a collision between two magnets, there may be a scattering of fragments in different directions. Protecting your eyes is crucial in such a situation.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
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. They can also damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
Keep neodymium magnets away from 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.
The magnet is coated with nickel - be careful if you have an 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 primarily characterized by their significant internal force. They attract to each other, and any object that comes in their way will be affected.
If the joining of neodymium magnets is not under control, at that time they may crumble and crack. You can't move them to each other. At a distance less than 10 cm you should have them very firmly.
Neodymium magnets should not be around children.
Neodymium magnets are not toys. Do not allow children to play 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 severe injuries, and even death.
Neodymium magnets are the most powerful magnets ever invented. Their power can surprise 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.
Neodymium magnets can become demagnetized at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties at high temperatures, it's important to note that the extent of this effect can vary based on factors such as the magnet's material, shape, and intended application.
Never bring neodymium magnets close to a phone and 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.
