Shopping tips
Advantages and disadvantages of neodymium magnets NdFeB.
In addition to their remarkable pulling force, neodymium magnets offer the following advantages:
- Their magnetic field is durable, and after around 10 years, it drops only by ~1% (according to research),
- They protect against demagnetization induced by surrounding electromagnetic environments remarkably well,
- Thanks to the glossy finish and silver coating, they have an elegant appearance,
- Magnetic induction on the surface of these magnets is very strong,
- 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 magnetic form),
- The ability for accurate shaping or customization to individual needs – neodymium magnets can be manufactured in many forms and dimensions, which enhances their versatility in applications,
- Wide application in modern technologies – they are utilized in HDDs, electric drives, clinical machines along with high-tech tools,
- Compactness – despite their small size, they provide high effectiveness, making them ideal for precision applications
Disadvantages of magnetic elements:
- They are fragile when subjected to a powerful impact. If the magnets are exposed to shocks, it is advisable to use in a metal holder. The steel housing, in the form of a holder, protects the magnet from cracks and reinforces its overall durability,
- They lose strength at elevated 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 sealed magnets, such as those made of plastic,
- The use of a protective casing or external holder is recommended, since machining internal cuts in neodymium magnets is restricted,
- Potential hazard related to magnet particles may arise, if ingested accidentally, which is crucial in the family environments. Furthermore, minuscule fragments from these magnets might hinder health screening once in the system,
- In cases of mass production, neodymium magnet cost may not be economically viable,
Handle Neodymium Magnets Carefully
Do not give neodymium magnets to children.
Neodymium magnets are not toys. Do not allow children to play with them. They can be a significant choking hazard. If multiple magnets are swallowed, they can attract to each other through the intestinal walls, causing significant injuries, and even death.
Avoid contact with neodymium magnets if you have a nickel 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, you can try wearing gloves or simply avoid direct contact with nickel-plated neodymium magnets.
Neodymium Magnets can attract to each other, pinch the skin, and cause significant injuries.
If the joining of neodymium magnets is not under control, then they may crumble and crack. You can't approach them to each other. At a distance less than 10 cm you should have them extremely strongly.
Neodymium magnets are fragile as well as can easily crack and shatter.
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. At the moment of connection between the magnets, small sharp metal fragments can be propelled in various directions at high speed. Eye protection is recommended.
Neodymium magnets can become demagnetized at high temperatures.
In certain circumstances, Neodymium magnets can lose their magnetism when subjected to high temperatures.
Neodymium magnets should not be near people with pacemakers.
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.
Make sure not to bring neodymium magnets close to the TV, wallet, and computer HDD.
Neodymium magnets generate intense magnetic fields that can destroy magnetic media such as floppy disks, video tapes, HDDs, credit cards, magnetic ID cards, cassette tapes, or other devices. They can also destroy videos, televisions, CRT computer monitors. Do not forget to keep neodymium magnets away from these electronic devices.
Do not bring neodymium magnets close to GPS and smartphones.
Neodymium magnets generate intense magnetic fields that interfere with magnetometers and compasses used in navigation, as well as internal compasses of smartphones and GPS devices.
Dust and powder from neodymium magnets are highly flammable.
Do not attempt to drill into neodymium magnets. Mechanical processing is also not recommended. Once crushed into fine powder or dust, this material becomes highly flammable.
Neodymium magnets are the most powerful magnets ever invented. Their power can shock you.
Familiarize yourself with our information to correctly handle these magnets and avoid significant swellings to your body and prevent disruption to the magnets.
Be careful!
So you are aware of why neodymium magnets are so dangerous, see the article titled How dangerous are strong neodymium magnets?.
