Question
Describe how the magnetic domains in an unmagnetized iron rod will respond to the presence of a strong external magnetic field. (a) The domains will split into monopoles.
(b) The domains will tend to align with the external field.
(c) The domains will tend to orient themselves perpendicular to the external field.
(d) The domains will tend to align so as to cancel out the external field.
