Explanation / Answer

here,

number of turns , N = 220 turns

area = 14 cm^2 = 14 * 10^-4 m^2

time interval , t = 0.04 s

magnetic feild , B = 5.2 * 10^-5 T

A)

the total flux through the loop , phi0 = N * area * B

phi0 = 220 * 14 * 10^-4 * 5.2 * 10^-5 Wb

phi0 = 1.6 * 10^-5 Wb

B)

the total flux through the loop after the rotation , phi = 0 Wb

C)

the EMF induced , V = dphi /dt

V = ( 1.6 * 10^-5)/0.04 V

V = 4 * 10^-4 V
