The domain theory explains magnetic phenomenon by proposing the existence of domains. Domains are small regions within an object that are magnetic. These regions may be from one to hundreds of microns, which is small, but larger than atomic ... Magnets become demagnetized when heated or when hammered or dropped repeatedly.

Domain Theor ... The theory of ferromagnetism, based on electronic exchange forces, predicts the magnitude of Ms, but says nothing about the direction of Ms. Experimentally, it is observed that for a homogeneous specimen at constant temperature, the magnitude of Ms is uniform but the direction of Ms is in general not...

"Domain wall pinning" is another factor in making domain walls harder to move; this is like driving a pile into the ground to keep the domain wall from moving. Domain theory is useful in understanding how magnets work.

In the first step, dielectric constitutive relations are obtained through consideration of Langevin, Ising spin and preferred orientation theory with domain interactions incorporated through mean field relations. This yields a model for the anhysteretic polarization that occurs in the absence of domain wall pinning.
