Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
Apart from their superior power, neodymium magnets have these key benefits:
- Their magnetic field is maintained, and after approximately 10 years, it drops only by ~1% (theoretically),
- They protect against demagnetization induced by ambient magnetic fields remarkably well,
- In other words, due to the glossy gold coating, the magnet obtains an aesthetic appearance,
- The outer field strength of the magnet shows elevated magnetic properties,
- With the right combination of magnetic alloys, they reach excellent thermal stability, enabling operation at or above 230°C (depending on the form),
- The ability for accurate shaping as well as adjustment to specific needs – neodymium magnets can be manufactured in many forms and dimensions, which extends the scope of their use cases,
- Significant impact in advanced technical fields – they are utilized in computer drives, rotating machines, medical equipment or even sophisticated instruments,
- Thanks to their power density, small magnets offer high magnetic performance, while occupying minimal space,
Disadvantages of magnetic elements:
- They can break when subjected to a strong impact. If the magnets are exposed to physical collisions, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from damage , and at the same time enhances its overall resistance,
- They lose power at high temperatures. Most neodymium magnets experience permanent loss 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,
- They rust in a wet environment. For 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 fine details in neodymium magnets is difficult,
- Potential hazard from tiny pieces may arise, in case of ingestion, which is important in the health of young users. It should also be noted that miniature parts from these products can complicate medical imaging after being swallowed,
- In cases of mass production, neodymium magnet cost may be a barrier,
Safety Guidelines with Neodymium Magnets
Neodymium magnets can demagnetize at high temperatures.
Whilst Neodymium magnets can lose their magnetic properties 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.
Keep neodymium magnets away 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.
The magnet coating is made of nickel, so be cautious if you have an allergy.
Studies clearly indicate a small percentage of people who suffer from metal allergies such as 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 highly flammable.
Avoid drilling or mechanical processing of neodymium magnets. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets should not be near people with pacemakers.
Neodymium magnets generate very strong magnetic fields that can 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.
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.
Neodymium magnets bounce and clash mutually within a distance of several to around 10 cm from each other.
Keep neodymium magnets away 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.
Never bring neodymium magnets close to a phone and GPS.
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.
Neodymium magnetic are highly delicate, they easily break and can crumble.
In the event of a collision between two neodymium magnets, it can result in them getting chipped. They are coated with a shiny nickel plating similar to steel, but they are not as hard. 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.
Neodymium magnets are the most powerful magnets ever invented. Their strength can shock you.
