When a Ferromagnetic Material Placed in Magnetizing Field?

When a piece of ferromagnetic material is placed into an external magnetic field, two things happen. The spins in each domain shift so that the magnetic moments of the electrons become more aligned with the direction of the field.

When a ferromagnetic material is placed in external magnetic field?

Atoms of ferromagnetic material in unmagnetised state form domains inside the ferromagnetic material. These domains have large magnetic moments due to the magnetic moment of atoms. In the absence of magnetic field, these domains have magnetic moment in different directions.

When a ferromagnetic material is placed in an external magnetic field the net magnetic field of its magnetic domains becomes?

When a ferromagnetic material is in the unmagnetized state, the domains are nearly randomly organized and the net magnetic field for the part as a whole is zero. When a magnetizing force is applied, the domains become aligned to produce a strong magnetic field within the part.
