Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their exceptional magnetic power, neodymium magnets offer the following advantages:
- They retain their attractive force for nearly ten years – the drop is just ~1% (in theory),
- They protect against demagnetization induced by external electromagnetic environments remarkably well,
- By applying a shiny layer of gold, the element gains a sleek look,
- They have exceptional 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 customized forming and precise design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
- Significant impact in new technology industries – they are utilized in data storage devices, rotating machines, diagnostic apparatus as well as other advanced devices,
- Thanks to their concentrated strength, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of rare earth magnets:
- They are fragile when subjected to a strong impact. If the magnets are exposed to physical collisions, they should be placed in a steel housing. The steel housing, in the form of a holder, protects the magnet from damage and reinforces its overall resistance,
- They lose power at extreme temperatures. Most neodymium magnets experience permanent degradation 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 advisable to use sealed magnets made of synthetic coating for outdoor use,
- Using a cover – such as a magnetic holder – is advised due to the restrictions in manufacturing threads directly in the magnet,
- Potential hazard from tiny pieces may arise, especially if swallowed, which is important in the health of young users. It should also be noted that miniature parts from these magnets might complicate medical imaging when ingested,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Exercise Caution with Neodymium Magnets
It is important to keep neodymium magnets out of reach from children.
Not all neodymium magnets are toys, so do not let children play with them. In the case of small magnets, they can be swallowed and cause choking. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
It is crucial not to allow the magnets to pinch together uncontrollably or place your fingers in their path as they attract to each other.
Magnets will crack or crumble with careless connecting to each other. Remember not to approach them to each other or have them firmly in hands at a distance less than 10 cm.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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. 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 demagnetize 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.
Neodymium magnets are among the most powerful magnets on Earth. The astonishing force they generate between each other can surprise you.
On our website, you can find information on how to use neodymium magnets. This will help you avoid injuries and prevent damage to the magnets.
Magnets made of neodymium are noted for their fragility, which can cause them to crumble.
Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crumble. Neodymium magnets are made of metal and coated with a shiny nickel, but they are not as durable as steel. At the moment of connection between the magnets, small metal fragments can be dispersed in different directions.
Neodymium magnets are not recommended for people with pacemakers.
Neodymium magnets generate strong magnetic fields. As a result, they interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them 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.
Never bring neodymium magnets close to a phone and GPS.
Strong fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
