A certain amount of current flows through a ring shaped coil with fixed number of turns. How does the magnetic induction B varies inside the coil if an iron core is threaded into coil without dimensional change of coil?

Decreases
Increases
Remains same
First increases and then decreases depending on the depth of iron in¬sertion
