Domain is a region in a ferromagnetic material where all the magnetic dipole moments are aligned. The domains are of microscopic size of the order of 10-8 to 10-12 m3 and contains about 1015 to 1017 atoms. Each atom of a domain has magnetic moment in the same direction and gives a resultant large magnetic moment to the domain.
