Question

why do iron is called "soft magnetic material"?​

Answer 1

A soft magnetic material means it can be magnetized and de-magnetized. A hard magnet stay magnetized and it difficult to demagnetize. Iron and iron based alloys are often used for soft magnetic applications (such as electromagnet) because iron is one of the best elements to accept magnetic field and become a magnet.
