China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Neodymium magnets are widely used in all kinds of industries and daily life because of their excellent magnetic properties. The answer to the question of whether neodymium magnets will wear out is yes, and it should be noted that “wear out” here mainly refers to physical wear and tear or chemical corrosion, rather than the loss of magnetic properties.
Physical Wear Out
Under friction or impact, the surface of neodymium magnets may experience wear and tear. For example, the contact between magnets and other materials, or when used in moving parts, can cause their surfaces to gradually wear out, and this physical damage may affect the shape and appearance of the magnet.

Chemical Corrosion Wear
Neodymium magnets are particularly sensitive to certain environmental conditions, especially humidity and salt spray environments, which can lead to corrosion on the magnet surface. Corrosion not only damages the magnet's appearance, but may also reduce its magnetic properties. To prevent this, neodymium magnets are often coated with a treatment, such as nickel plating, to improve their corrosion resistance and durability.
Possible effects of neodymium magnet wear
The main effects are magnetic degradation, danger (fragments after wear may be very sharp, similar to broken glass, easy to cause cuts), equipment failure, etc. In order to avoid the effects, it is recommended to take appropriate protective measures, such as regular inspection of the state of neodymium magnets, timely replacement of magnets that have been severely worn out.
In order to prolong the service life of neodymium magnets, anti-corrosion coating should be used, avoiding shocks, reasonable storage and regular inspection.
