A very small circular loop of radius a is initially (at t=0) coplanar and concentric with a much larger fixed circular loop of radius b. A constant current I flows in the larger loop. The smaller loop is rotated with a constant angular speed ω about the common diameter. The emf induced in the smaller loop as a function of time t is
Options
(a) πa²μ₀I/2b ω cos ωt
(b) πa²μ₀I/2b ω sin ω²t²
(c) πa²μ₀I/2b ω sin ωt
(d) πa²μ₀I/2b ω sin² ωt
