A solenoid having an iron core has its terminals connected across an ideal `DC` source and it is in steady state.If the iron core is removed the current flowing through the solenoid just after removal of rod

A

increases

B

decreases

C

remains unchanged

D

nothing can be said

Text Solution

Verified by Experts

The correct Answer is:
A
Current will have to increase in order to oppose the cause (decrease in field).
