Advantages and disadvantages of neodymium magnets NdFeB.

In addition to immense power, neodymium magnets have the following advantages:

• They do not lose their strength (of the magnet). After approximately 10 years, their strength decreases by only ~1% (theoretically),
• They are highly resistant to demagnetization by external magnetic field,
• In other words, thanks to the glossy nickel, gold, or silver finish, the element gains an visually attractive appearance,
• They have very high magnetic induction on the surface of the magnet,
• Magnetic neodymium magnets are characterized by hugely high magnetic induction on the surface of the magnet and can operate (depending on the form) even at temperatures of 230°C or higher...
• Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in many variants of shapes and sizes, which expands the range of their possible uses.
• Wide application in the industry of new technologies – are utilized in hard drives, electric motors, medical equipment and various technologically advanced devices.

Disadvantages of neodymium magnets:

• They can break as they are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and also increases its overall strength,
• Magnets lose their power due to exposure to high temperatures. In most cases, when the temperature exceeds 80°C, these magnets experience permanent loss in strength (although it is worth noting that this is dependent on the form and size of the magnet). To avoid this problem, we offer special magnets marked with the [AH] symbol, which exhibit high temperature resistance. They can operate even at temperatures as high as 230°C or more,
• They rust in a humid environment. For outdoor use, we recommend using waterproof magnets, such as those made of rubber or plastic,
• The use of a cover - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
• Health risk to health from tiny fragments of magnets pose a threat, when accidentally ingested, which is particularly important in the context of children's health. Furthermore, miniscule components of these magnets are able to complicate diagnosis in case of swallowing.
