Question

Asseration: An emf is induced in a along solenoid by a bar magnet that moves while totally inside it along the solenoid axis.
Reason: As the magnet moves inside the solenoid the flux through individual turns of the solenoid changes.
A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.
C. Statement-1 is True, Statement-2 is False.
D. Statement-1 is False, Statement-2 is True.

Answer 1

Correct Answer - D
Even though flux through individual lines changes, it remains unchanged for the solenoid as a whole. Therefore no emf is induced in the long solenoid.
