Shopping tips
Advantages as well as disadvantages of neodymium magnets NdFeB.
Besides their stability, neodymium magnets are valued for these benefits:
- Their power is maintained, and after around ten years, it drops only by ~1% (theoretically),
- They show superior resistance to demagnetization from external magnetic fields,
- Thanks to the glossy finish and nickel coating, they have an aesthetic appearance,
- Magnetic induction on the surface of these magnets is impressively powerful,
- Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C or more,
- Thanks to the possibility in shaping and the capability to adapt to unique requirements, neodymium magnets can be created in different geometries, which broadens their application range,
- Significant impact in advanced technical fields – they are used in data storage devices, electric drives, clinical machines or even technologically developed systems,
- Compactness – despite their small size, they generate strong force, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are fragile when subjected to a heavy impact. If the magnets are exposed to shocks, it is suggested to place them in a steel housing. The steel housing, in the form of a holder, protects the magnet from cracks and enhances its overall durability,
- They lose magnetic force at extreme temperatures. Most neodymium magnets experience permanent loss in strength when heated above 80°C (depending on the dimensions and height). However, we offer special variants with high temperature resistance that can operate up to 230°C or higher,
- They rust in a damp environment. For outdoor use, we recommend using encapsulated magnets, such as those made of rubber,
- Using a cover – such as a magnetic holder – is advised due to the challenges in manufacturing fine shapes directly in the magnet,
- Health risk from tiny pieces may arise, when consumed by mistake, which is significant in the protection of children. It should also be noted that tiny components from these assemblies have the potential to interfere with diagnostics after being swallowed,
- Higher purchase price is one of the drawbacks compared to ceramic magnets, especially in budget-sensitive applications
Handle Neodymium Magnets with Caution
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.
Magnets will bounce and contact together within a radius of several to almost 10 cm from each other.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
The strong magnetic field generated by neodymium magnets can damage magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also damage videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Dust and powder from neodymium magnets are highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. If the magnet is crushed into fine powder or dust, it becomes highly flammable.
Neodymium magnets are the strongest magnets ever invented. Their power can surprise you.
Please review the information on how to handle neodymium magnets and avoid significant harm to your body, as well as prevent unintentional disruption to the magnets.
Neodymium magnetic are highly susceptible to damage, leading to breaking.
Neodymium magnets 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. At the moment of collision between the magnets, small metal fragments can be dispersed in different directions.
Keep neodymium magnets away from people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can interfere with the operation of a pacemaker. This happens because such devices have a function to deactivate them in a magnetic field.
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.
Do not bring neodymium magnets close to GPS and smartphones.
Intense magnetic fields generated by neodymium magnets interfere with compasses and magnetometers used in navigation, as well as internal compasses of smartphones and GPS devices.
Magnets should not be treated as toys. Therefore, it is not recommended for youngest children to have access to them.
Neodymium magnets are not toys. Be cautious and make sure no child plays with them. In the case of swallowing multiple magnets simultaneously, they can attract to each other through the intestinal walls. In the worst case scenario, this can lead to death.
Neodymium magnets can demagnetize at high temperatures.
Whilst 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.
