Magnetic domain
| Stan Zurek, Magnetic domain, Encyclopedia Magnetica, E-Magnetica.pl |
Magnetic domain - a region in a ferromagnetic or ferrimagnetic material, in which strong interatomic interactions cause for the magnetic moments to align over large macroscopic volumes. Magnetic domains are separated by domain walls.

Magnetic domains in a single grain (outlined with a black line) of non-oriented electrical steel. The photo shows an area 0.1 mm wide, and the arrows show orientation of the domains. The domains are separated by domain walls.
