Barkhauszen effect

When the specimen of a ferromagnetic material is magnetized by gradually increasing the magnetising fields, then the change of magnetic flux through the material is not continuous but in small discrete steps. Along the steep portion of the M-H magnetization curve, the discontinuous rotation of the magnetic domains give rise to Barkhauszen effect.
