do neodymium magnets rust?
 

Neodymium magnets are a popular choice for many applications due to their high strength and resistance to demagnetization. One common question people have about these magnets is whether or not they rust. The good news is that neodymium magnets do not rust!

This is because they are made of a combination of neodymium, iron, and boron, which are all non-corrosive materials. Additionally, these magnets are coated with a protective layer of nickel or another suitable material to prevent rusting.

However, it is important to note that although neodymium magnets themselves do not rust, they can still be affected by external factors such as moisture and humidity. If a neodymium magnet is exposed to extreme levels of moisture over an extended period of time, it can cause the protective coating to break down, which may lead to rusting.

To avoid any potential issues with rusting, it is recommended to store neodymium magnets in a cool, dry place, away from any sources of moisture or humidity. Additionally, if you are using neodymium magnets in an application where they will be exposed to moisture, it is important to ensure that they are properly sealed and protected to prevent any damage.
