Shopping tips

Advantages as well as disadvantages of neodymium magnets NdFeB.
In addition to their immense strength, neodymium magnets offer the following advantages:
- They have constant strength, and over around ten years their attraction force decreases symbolically – ~1% (according to theory),
- They show superior resistance to demagnetization from external magnetic fields,
- Because of the reflective layer of nickel, the component looks aesthetically refined,
- They possess strong magnetic force measurable at the magnet’s surface,
- Neodymium magnets are known for exceptionally strong magnetic induction and the ability to work at temperatures up to 230°C or higher (depending on the shape),
- With the option for tailored forming and precise design, these magnets can be produced in various shapes and sizes, greatly improving design adaptation,
- Key role in advanced technical fields – they are used in computer drives, electromechanical systems, medical equipment and sophisticated instruments,
- Relatively small size with high magnetic force – neodymium magnets offer intense magnetic field in tiny dimensions, which makes them useful in compact constructions
Disadvantages of magnetic elements:
- They may fracture 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 fracture while also increases its overall strength,
- High temperatures may significantly reduce the magnetic power 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,
- They rust in a wet environment – during outdoor use, we recommend using encapsulated magnets, such as those made of rubber,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is restricted,
- Health risk from tiny pieces may arise, when consumed by mistake, which is important in the context of child safety. Moreover, tiny components from these assemblies might hinder health screening when ingested,
- In cases of tight budgets, neodymium magnet cost may be a barrier,
Precautions
Magnets made of neodymium are extremely fragile, they easily fall apart as well as can crumble.
Neodymium magnetic are delicate and will crack if allowed to collide with each other, even from a distance of a few centimeters. They are coated with a shiny nickel plating similar to steel, but they are not as hard. At the moment of connection between the magnets, small sharp metal pieces can be propelled in various directions at high speed. Eye protection is recommended.
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.
If you have a nickel allergy, avoid contact with neodymium magnets.
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.
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 happens because such devices have a function to deactivate them in a magnetic field.
Neodymium magnets can become demagnetized at high temperatures.
Under specific conditions, Neodymium magnets may experience demagnetization when subjected to high temperatures.
Magnets will attract to each other, so remember not to allow them to pinch together without control or place your fingers in their path.
Neodymium magnets will jump and also clash together within a distance of several to almost 10 cm from each other.
Under no circumstances should neodymium magnets be placed near a computer HDD, TV, and wallet.
Neodymium magnets generate strong magnetic fields that can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, etc. devices. They can also damage videos, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Never bring neodymium magnets close to a phone and GPS.
Neodymium magnets are a source of strong magnetic fields that cause interference with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets are not toys, children should not play with them.
Neodymium magnets are not toys. You cannot allow them to become toys for children. Small magnets pose a serious choking hazard or can attract to each other in the intestines. In such cases, the only solution is to undergo surgery to remove the magnets, and otherwise, it can even lead to death.
Comparing neodymium magnets to ferrite magnets (found in speakers), they are 10 times more powerful, and their strength can shock 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.
