Question

What happens when a soft iron bar is instated in current carrying solenoid?

Answer 1

1. When a soft iron bar is instated in current carrying solenoid the strength of the magnetic field inside the solenoid is increases.
2. When a soft iron bar is place inside the solenoid the iron bar is magnetizes so increase the strength of iron bar.
3. Permeability of soft iron is much more than that of air or vacuum.

Hence, strength of magnetic field increases when soft iron is placed inside the solenoid.
