There is a uniform magnetic field (B) perpendicular to the plane of the figure in a circular region of radius a centred at O. ABCD is a conducing loop in the plane of the figure with its arms BC and DA along two radial lines from O having an angle `theta` between them. AB is circular arc of radius OB = d centred at O. CD is also a circular arc of radius `OC = b` centred at O. The magnetic field is changed at a rate `(dB)/(dt)`.

(a) The emf induced in the loop ABCD.
(b) Find emf induced in arc AB.
