A piece of unmagnetized iron at room temperature consists of iron atoms with randomly oriented magnetic moments microscopic domains each of which has a magnetic moment

Solution

A piece of unmagnetized iron at room temperature consists of microscopic domains each of which has a magnetic moment. The unmagnetized piece of iron is actually \"polycrystalline\" in nature. A single crystal consists of so many microscopic domains in that. The polycrystals are consist of single crystals. Since one single crystal carrries numerous numbers of domains, polycrystal will have very large numbers of domains. Since the polycrystals are consisting of single crystals, it will have different little crystals with orientation of crystallographic axes in every directions. Actually these cannot be considered as domains because domains are a part of single crystals eventhough, we are calling these polycrystalline things as domains.
