Advantages as well as disadvantages of neodymium magnets NdFeB.

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

• They do not lose their strength (of the magnet). After about 10 years, their power decreases by only ~1% (theoretically),
• They are highly resistant to demagnetization by external magnetic field,
• In other words, thanks to the shiny coating of nickel, gold, or silver, the element acquires an aesthetic appearance,
• They exhibit extremely 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 various forms and dimensions, which amplifies their universality in usage.
• Significant importance in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, 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 protective case. The steel housing in the form of a holder protects the magnet from impacts and simultaneously increases its overall strength,
• High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent reduction in strength (although it is dependent on the shape and size). To prevent this, we offer special magnets marked with the symbol [AH], which are highly resistant to high temperatures. They can operate even at temperatures up to 230°C, making them an ideal solution for applications requiring high-temperature operation,
• Due to their susceptibility to corrosion in a humid environment, we recommend using waterproof magnets made of rubber, plastic, or other moisture-resistant materials when using them outdoors,
• The use of a cover or a magnetic holder is recommended due to the limited possibilities of manufacturing threads or complex shapes in the magnet
• Potential hazard arising from small pieces of magnets can be dangerous, in case of ingestion, which is crucial in the context of children's health. Additionally, tiny parts of these magnets have the potential to complicate diagnosis when they are in the body.
