WebSep 12, 2024 · Within a domain, the magnetic dipoles are rigidly aligned in the same direction by coupling among the atoms. This coupling, which is due to quantum mechanical effects, is so strong that even thermal agitation at room temperature cannot break it. The result is that each domain has a net dipole moment. WebDomain walls move easily within the magnet and have a low coercivity. By contrast, a particle that is single-domain in all magnetic fields changes its state by rotation of all the magnetization as a unit. This results in a much larger coercivity. The most widely used theory for hysteresis in single-domain particle is the Stoner–Wohlfarth model. photo of clipboardWebDec 26, 2024 · When a material is placed in a magnetic field, the domains align themselves. Thus, the object itself effectively becomes a magnet.
