Advantages as well as disadvantages of neodymium magnets NdFeB.

Apart from immense power, 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 extremely resistant to demagnetization by external magnetic sources,
• By applying a shiny coating of nickel, gold, or silver, the element gains an aesthetic appearance,
• They possess very 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...
• The ability for precise shaping or customization to specific needs – neodymium magnets can be produced in many variants of shapes or sizes, which amplifies their universality in usage.
• Wide application in advanced technologically fields – are used in HDD drives, electric drive mechanisms, medical devices and very highly developed apparatuses.

Disadvantages of neodymium magnets:

• They are prone to breaking as they are extremely fragile when subjected to a powerful 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 simultaneously increases its overall strength,
• High temperatures can reduce the strength 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,
• 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 to health from tiny fragments of magnets pose a threat, when accidentally ingested, which is crucial in the context of child safety. It's also worth noting that miniscule components of these devices are able to be problematic in medical diagnosis when they are in the body.
