A uniform magnetic field is restricted within a region of radius r. The magnetic field changes with time at a rate
d B⃗/d t. Loop 1 of radius Rr 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
[NEET (Phase-II) 2016]
(a) -d B⃗/d tπ r^2 in loop 1 and zero in loop 2
(b) Zero in loop 1 and zero in loop 2
(c) -d B⃗/d tπ r^2 in loop 1 and -d B⃗/d tπ r^2 in loop 2
(d) -d B⃗/d tπ R^2 in loop 1 and zero in loop 2
