What happens to the domains in a ferromagnetic material when it is near a magnetic field?

Question

They start to line up but do not create a magnetic field.

They face the same direction creating a stronger magnetic field.

They remain the same, facing in all directions.

Answer 1

When a ferromagnetic material is exposed to an external magnetic field, the domains in the material begin to align in the direction of the magnetic field. This alignment leads to an increase in the net magnetic moment of the material, resulting in a stronger magnetic field. Therefore, the correct statement is:

They face the same direction creating a stronger magnetic field.
