Advantages and disadvantages of neodymium magnets NdFeB.

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

• They do not lose their power (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 shiny nickel, gold, or silver finish, the element gains an aesthetic appearance,
• They exhibit extremely high magnetic induction on the surface of the magnet,
• Thanks to their high temperature resistance, they can operate (depending on the form) even at temperatures up to 230°C and above...
• Thanks to the flexibility in shaping and the ability to adapt to specific requirements – neodymium magnets can be produced in various forms and dimensions, which enhances their versatility in applications.
• Significant importance in advanced technologically fields – are utilized in hard drives, electric drive mechanisms, medical equipment or various technologically 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 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,
• High temperatures can reduce the power of neodymium magnets. Typically, after heating above 80°C, most of them experience a permanent loss in strength (although it is dependent on the form 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,
• 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
• Health risk associated with microscopic parts of magnets are risky, in case of ingestion, which is particularly important in the context of children's health. Additionally, miniscule components of these devices are able to hinder the diagnostic process after entering the body.
