Advantages as well as 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 power decreases by only ~1% (theoretically),
• They are extremely resistant to demagnetization by external magnetic field,
• 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...
• Due to the option of accurate forming and adaptation to individual needs – neodymium magnets can be produced in a wide range of shapes and sizes, which amplifies their universality in usage.
• Key role in advanced technologically fields – find application in HDD drives, electric motors, medical devices or other highly developed apparatuses.

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,
• 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,
• 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 - a magnetic holder is recommended due to the limited production capabilities of creating threads or complex shapes in the magnet
• Health risk arising from small pieces of magnets can be dangerous, when accidentally ingested, which is crucial in the context of children's health. It's also worth noting that miniscule components of these products can be problematic in medical diagnosis after entering the body.
