I. A soft iron core is used in a moving coil galvanometer to increase the strength of magnetic
field.
II. From soft iron, more number of the magnetic lines of force passes.

Which of the following statement{s) is/are correct?

Soft iron is a ferromagnetic material and hence when it is used as a core in moving coil galvanometer, more number of magnetic field lines passes through it. Thus, the strength of
magnetic field and hence the sensitivity of galvanometer increases.
