Physics Help - Soft Magnetic Iron
This is called low hysteresis loss in science. This makes the soft iron best suitable for making electromagnets. A hard iron in contrast to soft iron retains the magnetism permanently.Conclusion for Soft Magnetic IronDue to its low carbon content and low hysteresis loss, soft magnetic iron is extensively applied in making electromagnets.

MAGNETIC MATERIALS (HARD AND SOFT) - what-when-how
There are a variety of alloys used with various combinations of magnetic properties, mechanical properties, and cost (Table M.5). There are seven major groups of commercially important materials: iron and low-carbon steels, iron-silicon alloys, iron-aluminum-silicon alloys, nickel-iron alloys, iron-cobalt alloys, ferrites, and amorphous .
