does the strength of solenoid increase if we keep iron inside?

Expert Answer:

Yes, when current passes through a solenoid, it produces its own magnetic field inside and outside the solenoid.
When a soft iron bar/core is placed inside the solenoid, it magnetizes the iron bar thereby increasing the strength of the magnetic field inside the solenoid.
