Unformatted text preview: . Saturation is achieved when this domain becomes oriented with the H field.
From saturation, as the H field is reduced by reversal of field direction, the curve does not retrace its
original path. A hysteresis effect is produced. At zero H field, there exist a residual B field that is called
the remanence, or remanent flux density, Br. To reduce the B field within the specimen to zero, as H
field of magnitude –Hc must be applied in a direction opposite to that of the original field; Hc is called the
