The temperature magnets lose magnetism
WebMar 13, 2024 · 1. Heat: The temperature change can cause demagnetization.At extreme temperature changes the atoms are rendered to moderate vibrations and with the increase of temperature beyond curie temperature the magnet will lose its magnetism. 2. Improper storage: If we store the magnets with north poles together it causes to lose its magnetism … WebApr 3, 2024 · So, the correct answer is “Option A”. Other reasons for a permanent magnet losing magnetism that are unrelated to time are heat, and exposure to a demagnetizing field. If a permanent magnet is heated beyond a point called the Curie temperature the heat will permanently disrupt the domain structure of the material and lose most of its ...
