Magnetization refers to the process by which a material becomes a magnet or acquires magnetic properties. This occurs when the magnetic moments of the atoms within the material align in a particular direction. Materials can be magnetized through various methods, including exposure to a strong external magnetic field or by passing an electric current through a coil wrapped around the material. The degree of magnetization depends on the material's magnetic susceptibility and the strength of the applied field. Permanent magnets are materials that retain their magnetization after the external field is removed, while temporary magnets lose most of their magnetism. The phenomenon of magnetization is fundamental to many technologies, including electric motors, generators, data storage, and medical imaging. Understanding how and why materials become magnetized is crucial in the study of electromagnetism and materials science.
