Question
A conductor loop of radius R is present in a uniform magnetic field B perpendicular the plane of the ring. If radius R varies as a function of time ′t′, as R = R0 + t. The e.m.f. induced in the loop is
Options
A.2π(R0 + t) B clockwise
B.π(R0 + t) B clockwise
C.2π(R0 + t) B anticlockwise
D.zero
Solution
φ = (πR2)B = πB(R0 + t)2
⇒
= 2πB(R0 + t) anticlockwise
⇒
= 2πB(R0 + t) anticlockwiseCreate a free account to view solution
