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 sources,
• In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
• They possess 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 or 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.
• Significant importance in advanced technologically fields – are used in HDD drives, electric drive mechanisms, medical equipment or various technologically advanced devices.

Disadvantages of neodymium magnets:

• They are fragile when subjected to a powerful impact. If the magnets are exposed to impacts, we recommend using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts, and at the same time increases its overall strength,
• Magnets lose their strength 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,
• Magnets exposed to a humid environment can corrode. Therefore, when using them outdoors, we suggest using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
• Limited ability to create threads or complex shapes in the magnet - the use of a housing is recommended - magnetic holder
• Health risk associated with microscopic parts of magnets pose a threat, when accidentally ingested, which becomes significant in the context of child safety. Additionally, small elements of these magnets can complicate diagnosis in case of swallowing.
