Magnetization is the process by which a material becomes magnetized, meaning it develops a magnetic field. This occurs when the magnetic moments of atoms within the material align in a specific direction, often due to an external magnetic field. The degree of magnetization depends on the material's properties and the strength of the applied field. Materials can be classified based on their magnetization behavior. For example, ferromagnetic materials, like iron, can retain their magnetization even after the external field is removed, while paramagnetic materials only exhibit magnetization in the presence of an external field. Understanding magnetization is essential in various applications, including electromagnets and magnetic storage devices.
