Describe how the magnetic domains in an unmagnetized iron rod will respond to the presence of a strong external magnetic field.
- The domains will split into monopoles.
- The domains will tend to align with the external field.
- The domains will tend to orient themselves perpendicular to the external field.
- The domains will tend to align so as to cancel out the external field.
This is College Physics Answers with Shaun Dychko. Because iron is ferro-magnetic, it has magnetic domains that will align with this external field that's applied.
