Ferromagnetic materials

Ferromagnetic materials are materials like iron, cobalt, and nickel that can become strongly magnetized. Their atoms have tiny magnetic regions called domains, each with a magnetic orientation. When exposed to a magnetic field, these domains align in the same direction, creating a strong, permanent magnetic effect. This alignment allows the material to attract or repel other magnetic objects. When the magnetic field is removed, some alignment remains, so the material stays magnetized. Ferromagnetic materials are commonly used in magnets, electric motors, and transformers due to their ability to maintain magnetic properties.
