{wiki=Ferromagnetic_materials}
Ferromagnetic materials are a class of materials that exhibit spontaneous magnetization, meaning they can become magnetized in the presence of an external magnetic field and retain that magnetization even after the external field is removed. This property arises from the alignment of magnetic moments associated with the atoms or ions in the material. Key characteristics of ferromagnetic materials include: 1. **Magnetization**: They can be strongly magnetized, resulting in a permanent magnetic field.
