Neodymium Iron Boron (NdFeB) magnets necessitate the use of a protective layer or surface treatment to guard against potential damage from corrosion. Exposure to atmospheric moisture alone can lead to signs of corrosion in an uncoated NdFeB magnet. Moreover, these magnets are exceptionally susceptible to corrosion in marine environments. Corrosion in these magnets, akin to rusting, results in an irreversible alteration of their structure. This leads to a gradual decline in their magnetic capabilities, causing the magnet to weaken over
