Relating to materials like iron, nickel, or cobalt that can be magnetized and retain their magnetism even after the external magnetic field is removed.
Iron is a ferromagnetic material, which means it can be magnetized easily.
Ferromagnetic is formed from "ferro-" (from Latin "ferrum", meaning iron) and "magnetic" (from Greek "magnetis", meaning of Magnesia, a region known for its magnetic properties). The term describes materials that are magnetically susceptible and can be magnetized, particularly those containing iron.
Think of 'iron' ('ferro-') which is known for its magnetic properties, helping you remember that 'ferromagnetic' refers to materials that can be magnetized.
