A long conductor AB lies along the axis of a circular loop of radius R. If the current in the conductor AB varies at the rate of I ampere/second, then the induced emf in the loop is
A
B
C
D
zero
Text Solution
Verified by ExpertsThe correct answer is:
D
Since magnetic field lines around the wire AB are circular, therefore magnetic flux through the circular loop will be zero, hence induced emf in the loop will be zero.
