Explanation:
According to domain theory, quantum mechanical exchange forces make magnetic moments of nearby atoms tend to point in the same direction. Collections of nearby atoms pointing in the same direction are called magnetic domains. ... The existence of sufficient exchange forces in some materials makes them ferromagnetic
