What is Domain?
In magnetism, a domain is a microscopic region within a ferromagnetic material in which all magnetic dipoles are aligned in the same direction. External magnetic fields cause domains to align, producing net magnetization. In proteins, domains are independently folding structural units.
Properties & Characteristics
In magnetism and chemistry, a domain refers to a small region within a ferromagnetic or ferrimagnetic material in which all magnetic moments are aligned in the same direction. Adjacent domains have different orientations, so the bulk material may be unmagnetised overall (random domain orientation) or magnetised (aligned domains). In chemistry, "domain" can also refer to a region of a VSEPR electron domain.
Uses & Applications
Magnetic domain theory explains hysteresis (permanent magnets, magnetic data storage), magnetic saturation, and demagnetisation. In VSEPR, "electron domain" (or electron group) determines molecular geometry. Understanding magnetic domains is essential for designing hard magnets (motors, speakers) and soft magnets (transformer cores).
Safety Information
Strong magnets used to manipulate magnetic domain materials can attract ferromagnetic objects at speed, causing injury. MRI machines involve powerful magnetic fields that can render certain domains hazardous for people with ferromagnetic implants.
