Magnets lose their properties when they are subjected to heating, hammering, or dropping from a height. Heating causes the magnetic domains, which were aligned, to gain energy and lose their orientation, leading to a loss of magnetic properties. Physical impacts like hammering or dropping cause misalignment of these domains, also resulting in loss of magnetism. Additionally, magnets can lose their strength due to exposure to strong electrical currents, corrosive environments, temperature fluctuations, and over long periods due to aging. The critical temperature known as the Curie temperature is a key point above which magnets lose their magnetic properties. Over time, even without external influences, magnets gradually lose strength due to disordered magnetic domains.
