Shopping tips

Advantages and disadvantages of neodymium magnets NdFeB.
Besides their stability, neodymium magnets are valued for these benefits:
- They virtually do not lose strength, because even after 10 years, the performance loss is only ~1% (in laboratory conditions),
- They remain magnetized despite exposure to magnetic noise,
- Thanks to the glossy finish and nickel coating, they have an elegant appearance,
- They exhibit extremely high levels of magnetic induction near the outer area of the magnet,
- 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 specific requirements, neodymium magnets can be created in different geometries, which broadens their functional possibilities,
- Significant impact in advanced technical fields – they find application in hard drives, electric motors, diagnostic apparatus and sophisticated instruments,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in tiny dimensions, which allows for use in compact constructions
Disadvantages of neodymium magnets:
- They can break when subjected to a powerful impact. If the magnets are exposed to physical collisions, we recommend in a protective enclosure. The steel housing, in the form of a holder, protects the magnet from fracture , and at the same time reinforces its overall strength,
- They lose field intensity at high temperatures. Most neodymium magnets experience permanent degradation 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 advisable to use sealed magnets made of plastic for outdoor use,
- Limited ability to create internal holes in the magnet – the use of a magnetic holder is recommended,
- Health risk linked to microscopic shards may arise, in case of ingestion, which is notable in the protection of children. Moreover, tiny components from these products can hinder health screening after being swallowed,
- In cases of mass production, neodymium magnet cost may not be economically viable,
Be Cautious with Neodymium Magnets
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.
People with pacemakers are advised to avoid neodymium magnets.
Neodymium magnets generate strong magnetic fields. As a result, they 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.
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, try wearing gloves or avoid direct contact with nickel-plated neodymium magnets.
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.
Magnets made of neodymium are particularly delicate, which leads to shattering.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. 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.
You should keep neodymium magnets at a safe distance from the wallet, computer, and TV.
Magnetic 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. In addition, they can damage televisions, VCRs, computer monitors, and CRT displays. You should especially avoid placing neodymium magnets near electronic devices.
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.
Neodymium magnets will jump and also contact together within a radius of several to almost 10 cm from each other.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times stronger, and their strength 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 demagnetize at high temperatures.
Although magnets have shown to retain their effectiveness up to 80°C or 175°F, this temperature may vary depending on the type of material, shape, and intended use of the magnet.
Neodymium magnets should not be in the vicinity youngest children.
Not all neodymium magnets are toys, so do not let children play with them. In such a situation, surgery is necessary to remove them. In the worst case scenario, it can result in death.
