On simple lattice systems with not too complex interactions this is just the point where all your spins are aligned in some particular direction. Saturation is most clearly seen in the magnetization curve (also called BH curve or hysteresis curve) of a substance, as a bending to the right of the curve (see graph at right). Methods. As we know that, where 0 = Permeability of free space = 4x10-7Tm/A. It shall be noted here that tough OA is also non linear but in this zone the rate of change of B with respect to increase in H is increasing which means that increasing the value of H increases the magnetic flux density B rapidly (How am I saying this? There are provided acicular berthollide particles comprising crystalline particles expressed by the formula FeOx (1.33 Ultrafast magnetization dynamics of hexagonal arrays of ferromagnetic nanodots shows transition between various collective dynamics with varying interdot separation promising their applications in magnetic storage, memory and communication devices. The magnetic flux density increases in the core with an increase of current. Eventually, at a certain external magnetic field, the domain walls have moved as far as they can, and the domains are as aligned as the crystal structure allows them to be, so there is negligible change in the domain structure on increasing the external magnetic field above this. The magnetic flux density does not increase beyond these points even after a drastic increase of magnetizing force. As we know that, B = 0rH. [10] The saturation current, the current through the winding required to saturate the magnetic core, is given by manufacturers in the specifications for many inductors and transformers.
