A uniform magnetic field is restricted within a region of radius r. The magnetic field changes with time at a rate 
. Loop 1 of radius R > r encloses the region r and loop 2 of radius R is outside the region of magnetic field as shown in the figure below. Then the e.m.f. generated is:
A
in loop 1 and zero in loop 2
B
zero in loop 1 and zero in loop 2
C
in loop 1 and 
in loop 2
D
in loop 1 and zero in loop 2
Text Solution
Verified by ExpertsThe correct answer is:
A
Induced e.m.f. in loop (1)
Induced e.m.f. in loop (2) Loop (2) is not in magnetic field so no field change so induced e.m.f.
