Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their pulling strength, neodymium magnets provide the following advantages:
- They retain their magnetic properties for almost ten years – the drop is just ~1% (based on simulations),
- They are very resistant to demagnetization caused by external magnetic sources,
- Thanks to the shiny finish and gold coating, they have an elegant appearance,
- They have very high magnetic induction on the surface of the magnet,
- These magnets tolerate high temperatures, often exceeding 230°C, when properly designed (in relation to form),
- With the option for fine forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving design adaptation,
- Significant impact in modern technologies – they are utilized in computer drives, rotating machines, medical equipment and technologically developed systems,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of rare earth magnets:
- They can break when subjected to a heavy impact. If the magnets are exposed to mechanical hits, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage while also strengthens its overall resistance,
- High temperatures may significantly reduce the field efficiency of neodymium magnets. Typically, above 80°C, they experience permanent deterioration 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 recommended to use sealed magnets made of rubber for outdoor use,
- Limited ability to create internal holes in the magnet – the use of a mechanical support is recommended,
- Health risk due to small fragments may arise, if ingested accidentally, which is significant in the protection of children. Moreover, small elements from these devices may interfere with diagnostics if inside the body,
- High unit cost – neodymium magnets are costlier than other types of magnets (e.g., ferrite), which increases the cost of large-scale applications
Exercise Caution with Neodymium Magnets
It is important to maintain neodymium magnets away from children.
Neodymium magnets are not toys. You cannot allow them to become toys for children. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
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.
Avoid bringing neodymium magnets close to a phone or GPS.
Neodymium magnets are a source of intense magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Neodymium magnets can become demagnetized at high temperatures.
While Neodymium magnets can demagnetize 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.
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 fragile and can easily break as well as get damaged.
Neodymium magnets are characterized by considerable fragility. Neodymium magnets are made of metal and coated with a shiny nickel surface, but they are not as hard as steel. At the moment of collision between the magnets, sharp metal fragments can be dispersed in different directions.
Neodymium magnets are among the most powerful magnets on Earth. The surprising force they generate between each other can surprise you.
Familiarize yourself with our information to properly handle these magnets and avoid significant injuries to your body and prevent damage to the magnets.
Neodymium magnets can attract to each other due to their immense internal force, causing the skin and other body parts to get pinched and resulting in significant swellings.
If 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 hold them extremely firmly.
You should maintain neodymium magnets at a safe distance from the wallet, computer, and TV.
The strong magnetic field generated by neodymium magnets 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 devices like video players, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Dust and powder from neodymium magnets are flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Warning!
