Advantages and disadvantages of neodymium magnets NdFeB.
Besides their durability, neodymium magnets are valued for these benefits:
- They virtually do not lose power, because even after 10 years, the decline in efficiency is only ~1% (based on calculations),
- Their ability to resist magnetic interference from external fields is notable,
- Because of the reflective layer of gold, the component looks visually appealing,
- They possess significant magnetic force measurable at the magnet’s surface,
- These magnets tolerate elevated temperatures, often exceeding 230°C, when properly designed (in relation to profile),
- With the option for fine forming and personalized design, these magnets can be produced in numerous shapes and sizes, greatly improving engineering flexibility,
- Significant impact in advanced technical fields – they find application in HDDs, rotating machines, medical equipment as well as sophisticated instruments,
- Relatively small size with high magnetic force – neodymium magnets offer strong power in small dimensions, which makes them useful in small systems
Disadvantages of magnetic elements:
- They are prone to breaking when subjected to a strong impact. If the magnets are exposed to external force, it is suggested to place them in a metal holder. The steel housing, in the form of a holder, protects the magnet from fracture while also strengthens its overall resistance,
- They lose strength at increased 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,
- Magnets exposed to wet conditions can degrade. Therefore, for outdoor applications, we recommend waterproof types made of rubber,
- The use of a protective casing or external holder is recommended, since machining threads in neodymium magnets is risky,
- Potential hazard from tiny pieces may arise, especially if swallowed, which is crucial in the health of young users. Furthermore, small elements from these assemblies can hinder health screening after being swallowed,
- Higher purchase price is an important factor to consider compared to ceramic magnets, especially in budget-sensitive applications
Notes with Neodymium Magnets
Neodymium magnetic are highly susceptible to damage, leading to breaking.
Neodymium magnets are highly delicate, and by joining them in an uncontrolled manner, they will crack. Magnets made of neodymium 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.
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 is because many of these devices are equipped with a function that deactivates the device in a magnetic field.
Neodymium magnets should not be in the vicinity youngest 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.
Do not place neodymium magnets near a computer HDD, TV, and wallet.
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 destroy devices like video players, televisions, CRT computer monitors. Remember not to place neodymium magnets close to these electronic devices.
Neodymium magnets can demagnetize at high temperatures.
Although magnets are generally resilient, their ability to retain their magnetic strength can be influenced by factors like the type of material used, the magnet's shape, and the intended purpose for which it is employed.
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.
Neodymium magnets are over 10 times stronger than ferrite magnets (the ones in speakers), and their power can surprise you.
Make sure to review all the information we have provided. This will help you avoid harm to your body and damage to the magnets.
Avoid bringing neodymium magnets close to a phone or GPS.
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.
Neodymium magnets can attract to each other, pinch the skin, and cause significant swellings.
If have a finger between or alternatively on the path of attracting magnets, there may be a large cut or a fracture.
The magnet coating contains nickel, so be cautious if you have a nickel 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.
