Advantages and disadvantages of neodymium magnets NdFeB.

Apart from immense power, neodymium magnets have the following advantages:

• They do not lose power over time. After about 10 years, their strength decreases by only ~1% (theoretically),
• They are exceptionally resistant to demagnetization caused by an external magnetic field,
• 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,
• By using an appropriate combination of materials, they can achieve high thermal resistance, allowing them to operate at temperatures up to 230°C and above...
• Due to the option of accurate forming or adaptation to individual needs – neodymium magnets can be produced in many variants of shapes or sizes, which enhances their versatility in applications.
• Wide application in modern technologies – are used in HDD drives, electric drive mechanisms, medical equipment or other advanced devices.

Disadvantages of neodymium magnets:

• They are fragile when subjected to a strong impact. If the magnets are exposed to impacts, we recommend using magnets in a protective case. 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 reduction 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 recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials,
• 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
• Possible danger associated with microscopic parts of magnets pose a threat, if swallowed, which becomes significant in the aspect of protecting young children. Furthermore, small elements of these magnets can hinder the diagnostic process after entering the body.
