What happens when an external magnetic field is applied to a ferromagnetic material?

Question

Accepted Answer

The material will possibly become a permanent magnet as a result of the overall magnetic moment becoming aligned with the direction of the applied field.

Answer

The alignment of the magnetic domains will remain stable and unchanged

Answer

Domain wall motion will occur where the magnetic domains that oppose the external field will grow as a result of the flux density of the external magnetic field.

Answer

Only the magnetic domains that are more or less aligned with the external magnetic field will grow, but the resulting magnetic moment will remain unchanged as domains opposing the field will still exist.
