In soft iron, the domains return to being randomly aligned when the field is removed. Hard iron is used in permanent magnets. To make a permanent magnet, a piece of hard iron is placed in a magnetic field. ... An electromagnet, in contrast, uses soft iron; this allows the field to be turned on and off.

Hard magnets have a high coercivity (Hc), and thus retain their magnetization in the absence of an applied field, whereas soft magnets have low values.
