Ferromagnetism is a property of certain materials that exhibit strong magnetic behavior due to the alignment of their magnetic moments in the same direction. This phenomenon occurs when the material's atomic structure allows for cooperative interactions among neighboring atoms, resulting in a net magnetization even in the absence of an external magnetic field. The historical discoveries related to magnetism highlighted ferromagnetism as a crucial aspect of how materials respond to magnetic fields, while understanding magnetic fields and lines helps to visualize how ferromagnetic materials interact within those fields.
