Ferromagnetism is a physical phenomenon in which certain materials, such as iron, nickel, cobalt, and some of their alloys, can exhibit strong magnetic properties. This characteristic arises from the alignment of magnetic moments (spins) of electrons in the material, which are typically arranged in parallel to each other within certain regions called domains. When these domains are aligned in the same direction, the material exhibits a strong magnetic field. The alignment can be influenced by an external magnetic field, and once removed, ferromagnetic materials can retain a significant amount of magnetization, known as remanence, making them ideal for use in permanent magnets.
