Any ferromagnetic or ferromagnetic material that is at a temperature below Tc is composed of small-volume regions in which there is a mutual alignment in the same direction of all magnetic dipole moments. Such a region is called a domain, and each one is magnetized to its saturation magnetization. Adjacent domains are separated by domain boundaries or walls across which the direction of magnetization gradually changes. Normally, domains are microscopic in size and for a polycrystalline specimen, each grain may consist of a single domain. Thus, in a microscopic piece of material, there will be large number of domains and all may have different magnetization orientations
