Curie point

The Curie point, named after physicist Pierre Curie, is the temperature at which certain magnetic materials lose their permanent magnetism and become paramagnetic. Below this temperature, materials like iron can be magnetized; however, once heated above the Curie point, their atomic structure changes enough that they can no longer hold a magnetic field. This temperature varies depending on the material, but it’s a crucial concept in understanding how temperature affects magnetism in various applications, from electronics to industrial machines.
