Answer: The correct answer is D.
Step-by-step explanation:
When the iron is placed in the magnetic field then it will magnetize and behave like a temporary magnet. The domains of the iron will align.
Magnetically soft material: It is an temporary magnet which is made from a material that is magnetized. It creates its own magnetic field. For example, magnetically soft material is an electromagnet. The direction of this material can be changed easily.
In the given problem, a magnetically soft material is placed in a strong magnetic field. The domains of the magnetically soft material are already aligned but when this material is placed in the magnetic field then the domains will easily realign.
Therefore, the magnetically soft material will become a temporary magnet because the domains will easily realign.
