Can Neodymium Magnets Be Used in Water?

Neodymium magnets are not naturally waterproof and can be damaged if exposed to water. When these magnets come into contact with water, especially over long periods, moisture can seep through cracks or flaws in the protective coating. This leads to rust, corrosion, and a gradual loss of magnetic strength. Standard neodymium magnets are usually coated with nickel, zinc, or epoxy for basic protection, but even these layers can fail over time. For applications that require direct contact with water, it’s best to use specially waterproofed neodymium magnets or add extra sealing measures. Proper care will ensure the magnet remains strong and functional.
