Advantages as well as disadvantages of neodymium magnets NdFeB.

In addition to immense strength, neodymium magnets have the following advantages:

• They do not lose their power (of the magnet). After approximately 10 years, their power decreases by only ~1% (theoretically),
• They are exceptionally resistant to demagnetization caused by an external magnetic field,
• Thanks to the shiny finish and nickel, gold, or silver coating, they have an aesthetic appearance,
• They have very high magnetic induction on the surface of the magnet,
• Magnetic neodymium magnets are characterized by very 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 and the ability to adapt to specific requirements – neodymium magnets can be produced in a wide range of shapes and sizes, which enhances their versatility in applications.
• Key role in advanced technologically fields – find application in HDD drives, electric drive mechanisms, medical equipment or very advanced devices.

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, it is suggested using magnets in a steel housing. The steel housing in the form of a holder protects the magnet from impacts and simultaneously 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 shape 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,
• Due to their susceptibility to corrosion in a humid environment, we suggest 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
• Health risk to health from tiny fragments of magnets pose a threat, if swallowed, which is particularly important in the context of children's health. It's also worth noting that small elements of these products have the potential to complicate diagnosis when they are in the body.
