The question of whether magnets wear out over time is a question that every user wonders. The power of magnets is constant. The magnet you bought will not lose its power over time. There is also no time limit for the magnet to lose its power. The magnet / magnet will retain its magnetic strength for centuries. The answer to the question of whether the power of magnets wear out over time: no. However, the only reason the magnet will lose its strength will be temperature. Depending on the type of magnet you use, the temperature resistance rate may vary. For example, the durability degree for NdFeB magnets is 115°C. With the finding of this temperature, your NdFeB magnet will start to lose its power or will lose its power. The answer to the question of whether the power of magnets will run out over time will be no if the magnet, that is, the magnet, is used under normal conditions. However, if the magnet is exposed to too much heat, this time its power will decrease.
